The QUBIK Project: The progress so far

Libre Space Foundation is devoted to the vision of open-source technologies in space, and for this, we often join forces with researchers, individuals, and teams who share this vision with us. One exciting project we have taken up is the QUBIK Project.

A few words about the Project

Our love for space has brought us in collaboration with Firefly Aerospace and the DREAM payloads program. This is a global competition to host academic and educational payloads as rideshare participants on the inaugural flight of the Firefly Alpha launch vehicle. For this project, we have been working together with FOSSA Systems and AMSAT EA. We have developed two PocketQube satellites, QUBIK-1 and QUBIK-2, and PICOBUS, a PocketQube deployer.

The satellites are expected to have a short lifespan of up to 3 weeks of orbit. Regardless of how short-lived they will be, though, they are built to perform Amateur radio experimentation. While those amateur radio experimentations will be taking place, the SatNOGS network of ground stations will be receiving signals from these satellites. By exploiting Doppler Variations, the network of ground stations will perform orbit determination and satellite identification as early as possible. This will utilize the benefits and the capabilities of the SatNOGS network to the fullest and demonstrate the Space Situational Awareness aspect of it.

How the Project has been progressing for the last few months

On the 12th of December 2019, the thermal vacuum test for the PICOBUS took place at Instituto Nacional de Técnica Aeroespacial, and on the 16th of the same month, the vibration test was conducted at the NanoSat Lab of the Polytechnic University of Catalunya. A few months later, on the 8th of February 2020, our team working at Hackerspace.gr completed the assembly of the PICOBUS and QUBIK-1 and QUBIK-2. The next day marked the bake out day for the project at the Institute of Electronic Structure and Laser. Lastly, on the 12th of February 2020, at the NanoSat Lab, the vibration acceptance campaign took place for PICOBUS, and so did the Protoflight campaign for QUBIK-1 and QUBIK-2. At this point in the process, the software is being developed so that the project will be able to facilitate all the amateur radio experiments that need to be carried out.

QUBIK-1, QUBIK-2, and the PICOBUS deployer form an exciting project for which we have worked hard, and we have collaborated with inspiring teams. As the development draws to completion we are excited to see what this project will achieve.

Space Situational Awareness – The story so far and an open way forward

An essay on the necessity of an open data approach for space.

With tens of thousands of objects being already in orbit and hundreds of thousands coming up in the near future, it is no secret that keeping track and predicting orbital attitude and position for those objects will become imperative for viable and sustainable space operations and explorations. Space Situational Awareness (or SSA for short) is a multi-million dollar effort undertaken by various agencies, governments, and organizations around the world many times combined with Space Weather and Near-Earth Objects tracking. Most (if not all) of those efforts are deeply rooted in their defense-related past. The military branches of their countries directly oversee many of them. For example, in the US, SSA services are operated by the 18th Space Control Squadron, a unit of the US Air Force, while in Russia, the 821st Main Centre for Reconnaissance of Situation in Space is operated under the Russian Space Forces. Inherently, running such services under a military branch imposes heavy restrictions with regards to data openness and transparency to operational capabilities of the Networks of radio and optical tracking equipment used by them.

Let’s have a more in-depth look into the current known efforts and their shortcomings when it comes to data openness.

The European Space Agency Space Surveillance and Tracking (SST) segment

The European Space Agency has been investing tens of millions of Euros since 2009 to develop a program around artificial objects tracking and orbit analysis. Unfortunately, between non-functional websites and awareness newsletter-style reports we have seen little of its actual technical data, let alone any open orbital data coming from it. Statistics do get shared from DISCOS (Database and Information System Characterizing Objects in Space) but the access to data is gated (restricted and request-only for certain entities). We should expect better from a publicly funded non-military organization.

Russian Military Space Surveillance Network (SKKP)

The SKKP is part of the Russian Space Forces (Космические войска России). The Network of multiple radars and ground stations across Russia was initially part of the missile early warning system of the Soviet Union and gradually gained its independence and specialization to detect satellites, identify them, and to discern their orbits. It maintains the Russian catalog of space objects, and provides data that could be used to support space launches, feed an anti-satellite program, and provides intelligence on hostile military satellites. It is the Russian equivalent of the United States Space Surveillance Network. No public data is available from SKKP.

The United States Space Surveillance Network (SSN)

The US SSN detects, tracks, catalogs, and identifies artificial objects orbiting Earth. The system is the responsibility of the Joint Functional Component Command for Space, part of the United States Space Command. Its facilities include dedicated and collateral sites around the world, consisting of tracking radars, detection radar, optical telescopes and imaging radars with systems like Ground-Based Electro-Optical Deep Space Surveillance (GEODSS) and Space Surveillance Telescope (SST). The data from SSN are analyzed by the Combined Space Operations Center (CSpOC), which also is part of the US Space Command. Besides its primary military function, CSpOC and the 18th Space Control Squadron are responsible for maintaining their space catalog of objects and running the SSA sharing program targeted to the US, foreign government, and commercial entities. This sharing and dissemination platform (space-track.org) has been the primary source of SSA data for most users worldwide. It has been fueling further dissemination platforms like Celestrak (with the additional analysis done by AGI). Although the nature of the data seems to be open and accessible with modern APIs and convenient formats, their license is highly restrictive. The license is restricted to personal use, banning further sharing of data or derivative data, to the point that most current usages of space-track.org data can most certainly be marked as illegal. That continuing legal threat, combined with the filtering of the data available concerning military payloads from the US and its allies, allow no doubts for the restrictive non-open data nature of space-track.org.

The Space Surveillance Network – Public Domain

Space Data Association (SDA)

SDA is an international organization of satellite operators working to, in part, enhance the “accuracy and timeliness of collision warning notifications.” The Association is driven by the member’s needs for in-time SSA information, with the members being mostly GEO satellite operators (EUTELSAT, INMARSAT, and others). The data shared amongst its members are not made public, and their source is the satellite operators themselves.

International Scientific Optical Network (ISON)

ISON is an international project, currently consisting of about 30 telescopes at about 20 observatories in about ten countries. ISON, as a civilian global space surveillance system, covers the whole GEO and is capable of searching and tracking objects both on GEO and various classes of HEO orbits (GTO, Molniya, etc.). From the published papers and reports coming from the network, it is clear that the tracking capabilities of ISON are quite capable. Unfortunately, there is limited dissemination of their data, gated, and only valid for the analysis of past observations, not for future permissions. Participation in the Network seems to be gated too since there is no clear path of joining or an established process to contribute.

The amateur satellite tracking community – SeeSat-L mailing list

A network of amateur satellite trackers provides positional measurements as well as orbital elements for a subset of objects, both in LEO, GEO, and HEO. This subset consists primarily of military payloads from the US and its allies (e.g., France, Germany, Israel, Japan) for which the 18th Space Control Squadron does not release orbital elements. This network originated from satellite trackers initially involved in Operation Moonwatch, the citizen scientist program, to track artificial satellites since the launch of Sputnik. Observers in this network are increasingly using more sophisticated sensors and software, increasing the accuracy of the orbital elements, as well as the number of objects that are tracked. Dissemination of data is open and readily available to the public, although confined mostly around the subset of objects that represent the group’s interest.

Various militaries

Various militaries around the world maintain a particular SSA capability, and in some cases, we do have public data around their existence. For example, the French military operates the GRAVES radar to track objects in predominantly LEO, while Germany operates GESTRA under GSSAC with multiple locations. Eight EU Member States (France, Germany, Italy, Poland, Portugal, Romania, Spain and UK), with representatives from National Designated Entities and Ministries of Defence and EU SatCen participate in the EUSST Cooperation, joining SST efforts. No data or orbital elements are made public.

The GRAVES system

Private companies

Commercialization of SSA services has been an approach that some private for-profit companies are exploring. Most notably, LeoLABS is providing paid SSA services for LEO objects, using data from their radar facilities. No data or orbital elements are made public.

The need for open data in SSA

We in Libre Space Foundation believe that all people shall have access to outer space, space technologies, and space data. Space Situational Awareness data are critical for our understanding, peaceful coexistence, and exploration of space. We believe that to achieve that, all SSA data should be gathered, processed, licensed, and disseminated as Open Data.
The benefits that Open Data can bring to SSA:

  • Transparency. Open Data supports public and comprehensive oversight of governmental and agency activities. For instance, Open Data makes it easier to monitor all space activities regardless of their classified or not status. It also encourages greater citizen participation in space affairs and supports verifiability, collaboration, and cross-checking of analysis.
  • Service Improvement. Open Data gives citizens and organizations the raw materials they need to engage in the space sector and contribute to the improvement of public SSA services. For instance, anyone can use Open Data to perform their orbital determination analysis and engage with existing services for improvement suggestions.
  • Efficiency. Open Data makes it easier and less costly for governments and agencies to discover and access their data or data from other organizations, which reduces acquisition costs, redundancy, and overhead. Open Data can also empower anyone with the ability to alert for gaps in public datasets and to provide more accurate information.
  • Innovation and Economic Value. Public data, and their re-use, are critical resources for social innovation and economic growth. Open Data provides new opportunities for governments and agencies to collaborate with anyone by giving open access to data about those services. Businesses and entities are using Open Data to understand potential markets better and build new data-driven products.

The open way forward

As Libre Space Foundation, we are committed to establish and act upon an open way forward around SSA. We will be guided by our principles, express them in our manifesto, examine the technical possibilities, and craft a development and implementation way ahead.

Principles

The following principles should guide space Situational Awareness:

Open Data
Unconstrained access to all data related to SSA, licensed appropriately, and treated as a public resource.

Modern technology stack
The technical implementation should be based on a modern technology stack, modular, expandable, and open source.

Verifiability
Due to the fundamental nature of the SSA data, we believe that verifiability should be an essential aspect of our data and processes, achieved through the openness of our technology stack, allowing for auditing by anyone.

Openness in participation
SSA data generation, processing, and consumption should be open for participation to all who wish to contribute without gated access.

Technical Possibilities

Sources of SSA data can be categorized in the following groups:

Active RF tracking
Essentially Radar systems emitting RF signals that then can be received and analyzed in a closed-loop order. This methodology is a high-cost, high-quality approach undertaken by most of the active SSA players currently (mostly governments through their military branches).

Passive RF tracking
Opportunistic RF tracking is an SSA surveying method utilizing pre-existing RF signal sources beyond someone’s control (radars or other transmissions), tracking the reflections on space objects from those sources. Given its nature, it can yield valuable results but, at the same time, is at risk of intermittent operations since one cannot have control over the origin of the RF source.

Signals (TM/TC&C)
Tracking signals (Telemetry or Telecommand and Control) from active space objects and specifically their doppler shift properties can yield substantial data that can be translated to quality SSA measurements. Although such an approach is limited to active space objects, it requires minimal development costs since it can utilize the existence of a global RF ground station network (like SatNOGS) without any additional changes needed to the space missions.

Optical
Optical tracking of visible light reflected upon space objects provides one of the best SSA data-producing methods. Readily available sensors, lenses, and mounts can be used to capture optical observations of space objects, yielding high-accuracy results. Its shortcomings are its dependence on sky and timing conditions and for some orbits its need for high-end costly optical systems (e.g., fast telescopes with sensitive sensors)

ID-tags and experiments in LEOP
A relatively modern and innovative approach would be to equip space objects with active or passive ID tags emitting identification codes passively or when probed, allowing for early identification and continuous tracking of those objects. Since this method requires additional development and cost for missions, it is imperative to standardize it and for a low-cost open-source implementation to be delivered, readily available for integration on future missions. Such an approach draws many parallels to existing models of tracking and monitoring on other domains (e.g., AIS for marine objects and ADSB for airborne objects) and also requires a legislative mandate to be effective, which in turn involves policy changes on a universal scale.

SatNOGS DB as a hub of information

SatNOGS DB has established itself as a hub on RF related information for hundreds of space missions so far. Given then the source of information is crowd-sourced and continues to expand, we believe that SatNOGS DB can be furtherly expanded to include SSA information and act as a hub for multiple sources of SSA data and their derivatives (orbital elements, conjunction reports, etc.) Since LSF develops SatNOGS DB as a modular project allowing for multiple sources and data consumers, we could envision an ecosystem where the processing of this data (automatic or manual) can also happen outside the SatNOGS DB instance and re-submitted for sharing through it. Collaboration with existing established hubs or information (like Celestrak/AGI) and up and coming open data approaches on specific subsets of SSA data (like TruSat) will be vital for establishing a collaborative and sustainable ecosystem around open SSA data. To that end, we will like to invite all possible collaborators to engage in our efforts and the public discourse around them.

SatNOGS DB

Obtaining open SSA data – Developments for Libre Space Foundation projects

The SatNOGS project provides natural extensions that will allow the Libre Space Foundation to provide open SSA data:

LEOP identification work

The SatNOGS network of ground stations observes satellites transmitting in the amateur VHF and UHF radio bands to demodulate and decode satellite telemetry. Telemetry is stored publicly in the SatNOGS database (SatNOGS DB). The observations rely on orbital elements provided by 18SPCS/CSpOC, redistributed by celestrak.com, CalPoly, or AMSAT, which are used to perform Doppler correction and antenna pointing. The combination of SatNOGS Network and SatNOGS DB allows LSF to provide independent data on the identification of satellites. Satellites with active transmitters can be identified through either a priori known transmitter frequencies, modulation schemes, and demodulated telemetry containing satellite call-signs. The orbital elements used for Doppler correction and antenna pointing allow LSF to determine which orbital elements match the observed frequencies of an identified satellite, hence linking a satellite to CSpOC orbital elements. LSF is currently already sharing this SSA data publicly with TS Kelso (Celestrak/AGI), as well as individual satellite operators. This functionality could be expanded to frequencies outside of the amateur VHF and UHF bands (i.e., 401MHz, 466MHz, S-band).

More information about this effort can be found in our satnogs-ops repository.

Tracking RF transmissions

LSF is currently developing functionality to extract Doppler curves from observations obtained through the SatNOGS network of ground stations. Observations are presently Doppler corrected using orbital elements by 18SPCS/CSpOC. Still, deviations of the observed frequencies, either from recorded spectrograms (waterfalls) or demodulated telemetry, can be used to obtain Doppler curves. These Doppler curves can be used to constrain orbital elements. They may allow LSF to generate a catalog of orbital elements to track satellites that are observed through the SatNOGS Network. This functionality would be available for actively transmitting satellites, and likely limited by the time accuracy and frequency stability of SatNOGS stations, as well as the frequency stability of the transmitter onboard the satellites.

Development of satnogs-network and satnogs-client are heavily influenced by this approach and you can track the progress on their respective repositories.

Doppler curve tracking and identification of signals through SatNOGS Network

Passive RF tracking

Currently not under development, but SatNOGS client/Network/DB could be expanded to include the estimation of orbital elements from active radar reflections, possibly using a set of dedicated stations spread over a region (e.g., Europe). Such an approach would generate Doppler curves and orbital elements for any object bright enough to be picked up, though only feasible if radars are active (outside of LSF control). We should explore the legal aspect of such an endeavor since there are unanswered questions around it in various jurisdictions.

Network of Optical Ground Stations

Building on the experience of designing the SatNOGS open-source framework for demodulating and decoding satellite telemetry using cheap off-the-shelf hardware, LSF is investigating developing a similar open-source framework for video and photo-based satellite tracking ground stations. Using recent CMOS technology as well as software development, automated detection, identification, and position determination of LEO satellites in video observations is feasible. This approach would generate positional measurements that serve as input to the determination of orbital elements of satellites, as well as to characterize the optical behavior of satellites.

LEOP and ID-tag experiments

Through the development of its next space missions QUBIK-1 and QUBIK-2, Libre Space Foundation is testing In-Orbit a set of technologies to allow for the earliest identification possible of a space object, based on its unique RF transmissions, using the global aspect of the SatNOGS Network.

Call for students: join us building open space technologies through Google Summer of Code 2020

Google announced today that Libre Space Foundation is among the mentoring organizations of Google’s Summer of Code 2020. This selection provides opportunities for students that would like to work full-time on open space technologies during their summer break and start participating in the Libre Space community.

Google Summer of Code is an annual program providing university students the chance to work on open -source projects during their summer break while earning a stipend!

If you are interested in working with open-source space technologies this summer, don’t hesitate to study the student guide thoroughly, and check our detailed instructions, with suggested ideas, or introduce your ideas for consideration.

Feel free to check the following video for a quick review of Google Summer of Code.

LSF head back to Orbit with the Qubik Mission

Libre Space Foundation is proud to announce that it is currently developing and integrating 2 pocketqube satellites (QUBIK-1 & QUBIK-2) and supplying a pocketqube deployer (PICOBUS) to be flown as part of the DREAM payloads program on the inaugural Firefly Alpha launch from Firefly Aerospace. 

An exploded view of the QUBIK satellites

Scheduled for launch around the end of the first quarter 2020 we are delighted to be taking part in this exciting mission. 

QUBIK mockup inside the clean box

The LSF contributors have been busy developing both the pocketqubes from scratch as well as the innovative deployment system that features a constant force spring design and, of course, all developments are being carried out using open source methodologies and licenses.

The satellites are expected to be short-lived with only ~3 weeks of predicted orbit lifespan. This short timeframe will be enough though for the communications experiment they are tasked to perform. Specifically, the satellites will be conducting a series of telecommunication related experiments, while at the same time, ground station analysis of the received signals will try to exploit doppler variations in order to perform orbit determination and satellite identification from radio amateur stations around the world. The telecommunication experiments will use several different modulation, coding and framing schemes, with the intention to provide insights about their performance at nano-pico-satellite missions. In addition, the frame itself will be organized in such a way so spacecraft identification can be performed as early as possible from the physical layer.

The brains of the QUBIK satellites will be the open source pocketqube format Communications board designed by LSF

You can follow along with the progress of our development in the relevant repositories or subscribe to Libre Space Foundation channels (LSF Forum Twitter Facebook ) for updates!

Work Begins on Space Library Projects.

Last week in Libre Space Foundation HQ in Athens LSF hosted the kick-off meeting of the Space Library project. Papadeas Pierros (Director of Operations, LSF) and Daina Bouquin (Head Librarian at Harvard–Smithsonian Center for Astrophysics) headed the meeting which was joined by many members of Libre Space Foundation. The Space Library is an initiative led by the staff team at Wolbach Librar in collaboration with the Libre Space Foundation and received funding from the Alfred P. Sloan Foundation. The goal is to help new communities participate in satellite missions, engender public engagement in space science, and to fuel new research by improving access to scientific research artifacts and supporting their reuse. To achieve this our team is developing open metadata standards and enabling public engagement with space technology in public libraries.  For example the MetaSat project is a project to develop and prototype an open metadata schema to link data, software, and hardware from small satellite missions. The schema will be designed and piloted using SatNOGS and it’s success will be assessed by seeking feedback from the various users, teams and contributors involved in SatNOGS. It was a pleasure to welcome Daina and we look forward to this exciting work developing.

Libre Space Foundation partners with Harvard’s Wolbach Library to launch Space Library funded by Sloan Foundation

The Wolbach Library at the Center for Astrophysics and the Libre Space Foundation recently received funding from the Alfred P. Sloan Foundation to create new infrastructure to support small satellite missions and enable public engagement with space technology.

These efforts are part of the “Space Library,” a new multicomponent initiative at Wolbach that is working to fuel new research by improving access to scientific research artifacts and supporting their reuse. The funding provided by the Alfred P. Sloan Foundation will support two specific Space Library projects: MetaSat and the Library Space Technology Network (LSTN).

The Space Library’s first project, MetaSat, will develop and prototype an open metadata schema. This schema will provide both a comprehensive structure and uniform standards for describing research objects produced by small satellite missions so they can be more easily found and used by others. Example schema components include standard ways to document dates, locations, people, datasets, and software.

This schema will subsequently be piloted on SatNOGS, the Libre Space Foundation’s open source network of satellite ground stations (on-ground technology that communicates with satellites). Wolbach Library also plans to install five ground stations at public libraries around the world. These five libraries will be the first participants in LSTN, a public-facing program that will provide opportunities for new communities to engage with and support real space missions. LSTN participants will give feedback on the MetaSat schema and the newly installed ground stations to ensure that even satellite novices are able to use these tools. If the pilot is successful, Wolbach hopes to expand LSTN and develop educational materials to support participating communities.

“I’m elated about this opportunity. We have a unique chance here to partner with people developing bleeding edge technologies while addressing questions that I think are foundationally important to the future of scientific research,” said Daina Bouquin, Head Librarian and PI of the Space Library. “Questions like, how do we link hardware, software, and data so people can fully share their knowledge and experience? Can we develop tools for scientists that are approachable to the public? These questions aren’t specific to space-based science, and I think librarians are strategically situated to help, so I’m thrilled to move forward.”

Libre Space Activity Update 2019-03-27

MIT, Beyond the Cradle 2019

Members of the LSF team travelled to attend and speak at the “Beyond the Cradle” event held at MIT in Boston in the US. This lively conference was focused on envisioning a new space age and as such had a plethora of speakers from a diverse range of areas of the space community.

Pierros Papadeas spoke about the broad aims of Libre Space Foundation and the milestones so far, of course focusing on UPsat and SatNOGS as well as over viewing the open source working methodologies of our global contributors.

European Space Agency Advanced Manufacturing Workshop

Members of Libre Space Foundation attended the European Space Agency Advanced Manufacturing Workshop held at the ESTEC facility in the Netherlands. A packed couple of days with overviews of current state of the art advanced manufacturing processes being presented and also working groups discussing and debating how to increase the relevance of advanced manufacturing techniques in the space sector. LSF team keenly promoted the notion of open source approaches and certainly utilising this approach for developing some responses to the problems in post/concurrent processing, metrology and quality checks that seemed prevalent barriers reducing the uptake of emergent additive manufacturing methods. Around the workshop timetable LSF team managed to network well and identified some parties interested in SatNOGS station development and also met with ESA staff to discuss potential ESA projects LSF may be interested in applying to join.

FOSDEM 2019 Report

The Libre Space Foundations team and contributors attended a snowy FOSDEM to promote Libre Space and to work together on the various LSF projects. Around 21 regular contributors spent a lot of time together working in the apartment the LSF team had booked and it was wonderful to see the community meeting in real life and seeing the passion they have for Libre Space Foundation.

Much of the work in the apartment was around SatNOGS however wider LSF projects, rocketry, pocketqube and PQ9ish were also being developed and discussed.

We managed both days at FOSDEM to have a small booth in the AW building and they were extremely well attended. A huge amount of people stopped to talk and to ask questions and many expressed an interest in building a SatNOGS station. The UPsat model and story continues to enthral people which is a fabulous legacy of the mission and the Pocketqube hardware again ignites interest in satellites and the miniaturisation of electronics for space.

Whilst at FOSDEM numerous talks were delivered around LSF projects, and in particular the work on SDR makerspace. Nestoras Sdoukis delivered an excellent update on GR-Soapy. Alex Csete spoke about the SDR Makerspace as a whole, including information and updates around gr-leo and investigations of the IQ database.

Libre Space contributors visited many stands/booths and talks relating to LSF activity. It was great to see SatNOGS contributors showing the Grafana people the public dashboards we are making for SatNOGS. It was obvious the Grafana team were thrilled to see their work being used for such an innovative project. LSF contributors attended KiCAD talks and liased with Gitlab and many other of the open source tools and platforms utilised in LSF work.

Finally we wanted to thank everyone who came either as an LSF contributor, team member or the many hundreds of you who stopped at the booth for a chat. Chatting to you at and since the event leaves us invigorated and inspired to be part of this global team claiming space, the Libre way.

  • Jo Hinchliffe
  • Fabian Schmidt
  • Patrick Dohmen
  • Cees Bassa

All four of them have been contributing tirelessly to our projects, in
meaningful ways, therefore it was only right to welcome them and include them as team contributors.

Busy times in the SatNOGs community

It’s been a big week behind the scenes at SatNOGS with a migration of the database performed and a change to enable a single sign on across all SatNOGS sites. These changes went extremely well and we thank the team who worked hard to make it happen. Also this week the community have been hunting for satellites launched on the Rocketlab ELaNA launch, capturing an ARISS scheduled contact and much more! Info on these and other SatNOGS activities can be seen here on the SatNOGS page.

SDR Makerspace and Fosdem

The SDR makerspace are pleased to announce that Alexander Csete is confirmed to speak about the project at next years FOSDEM. Its great to see our SDR makerspace project develop and gain some momentum.

Open Source Cubesat Workshop ’17

A few days ago Libre Space Foundation, the Librecube Initiative and European Space Agency’s European Space Operation Center Cybernetics Team came together and co-organized Open Source Cubesat Workshop ’17 (or OSCW17 for short) at the European Space Operations Center Headquarters in Germany.

For two days, the European Space Operation Center opened its doors to our community building open-source space technologies. We had the chance to watch, participate and get inspired by talks, pitches, and workshops that took place during OSCW.

We want to thank our hosts, the awesome people of ESOC, its director that keynoted the event, the Cybernetics team, and numerous ESA volunteers that took time off their schedules to join us.  would also like to thank the OSCW17 sponsors that placed their trust on open-source. And most importantly we must thank the awesome international community of researchers, industry representatives and individuals that joined us working together and collaborating on open-source space technologies.

The ESOC media team made all video recordings available to share. We aren’t going single out a few talks, pitches or workshops, Feel free watch all the talks (abstracts and slides linked in the video descriptions) in the following YouTube playlist, and don’t hesitate to join our continuous work on open-source space technologies in our community discussion forum and chat room.

Successful deployment of UPSat, the first open source satellite

UPSat, the first open source hardware and software satellite, was released in orbit by NanoRacks deployer from the International Space Station at 08:24 UTC 2017-05-18. After 30 minutes, UPSat subsystems commenced normal operations in orbit. The SatNOGS open ground station network started receiving telemetry signals from UPSat in several ground-stations deployed globally shortly after its deployment. All subsystems are reporting nominal operations and the UPSat team is proceeding​ with LEOP phase in preparation for the science phase of the mission.

Libre Space Foundation has a new home – libre.space

A few days ago Libre Space Foundation got access to the “libre.space” domain due to a generous contribution of the original owner of the domain and member of the SatNOGS community Matt Carberry.

We are looking forward to use this domain not only for Libre Space Foundation initiatives, such us SatNOGS and UPSat, but want to also provide a platform to share knowledge, discuss and co-operate on any open source hardware & software related to space.

For those reasons, we decided on expanding the SatNOGS community forum based originally at community.satnogs.org to community.libre.space. As an early example, Gpredict community (headed by A.Csete) has started utilizing our forum for their coordination needs and aims on utilizing the transmitter data provided by the SatNOGS DB

We aim for more open source collaboration in space in the future, don’t hesitate to join us.

Launch services for CANSAT Greece 2017

On April 19th 2017 Libre Space Foundation launched 5 High Power Rockets for 2017 CANSAT Greece student contest.

The weeks prior the contest day, Libre Space Foundation electronics lab and workshop where open for the student teams who needed equipment not readily available in their school.

Aiming to provide a scaled down satellite delivery and launch experience for students, Libre Space Foundation orchestrated payload certification, delivery as well as a detailed launch operation scenario for the rocket launches.

Students experienced the technical challenges regarding satellite certification, the silent moment during the countdown for lift off, the thrill of watching their payload soar into the sky and the excitment following parachute deployment, a sign that their mission is one step closer to success.

The first open source hardware satellite is delivered

The UPSat team of engineers is proud to announce the delivery of the first completely open source software and hardware satellite!

A major step towards UPSat’s launch has being completed. Its successful delivery to Innovative Solutions In Space (ISISpace) took place on August 18th in Delft, Netherlands. UPSat is the first complete delivery to ISISpace as part of the QB50 project. Engineers from the University of Patras and Libre Space Foundation, the makers of UPSat, in cooperation with Von Karman Institute and ISISpace engineers have successfully concluded all checkout tests anddelivery procedures, to enable UPSat’s integration to the NanoRacks launch system.

UPSat will be delivered to Orbital ATK, and then launched to the International Space Station via a Cygnus automated cargo spacecraft scheduled for 30th of December 2016. After successful docking to ISS, UPSat will be launch by the NanoRacks deployment pod aboard ISS.

This delivery marks a major milestone towards the realization of Libre Space Foundation vision foran open source ecosystem in space, while also being the first satellite designed and manufactured in Greece.
