Qubik

Libre Space Foundation 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. 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 ground stations around the world though the SatNOGS Network.
