Libre Space Foundation designed, developed, integrated and delivered 2 PocketQube satellites (QUBIK-1 & QUBIK-2) as well as a PocketQube deployer (PICOBUS) to be flown as part of the DREAM payloads program on the inaugural Firefly Alpha launch from Firefly Aerospace. The satellites are expected to be short-lived with only ~3 weeks of predicted orbit lifespan. This short timeframe though will suffice for a series of amateur radio experiments which are scheduled to be conducted.
The PocketQubes are tasked to perform Launch and Early Operations Phase (LEOP) Satellite Identification and Tracking experiments. Among the objectives of the experiments is to be able to unambiguously identify satellites early on after deployment, and to be able to generate and update existing orbital elements based on Doppler curve tracking. These objectives must be explored in a scalable, distributed and open-source way consistent with the Principles of the Libre Space Manifesto. The fourth objective of the experiments focuses on an in-orbit validation of a re-usable open-source PocketQube Platform.
In order to explore possible solutions to these objectives, the QUBIK mission will provide the environment for in-orbit demonstrations combined with experiments on ground segments from ground stations around the world through the SatNOGS Network.
PocketQubes QUBIK-3 and QUBIK-4 will be launched onboard Firefly Aerospace’s Flight 2 #ToTheBlack.
