Abstract EN
The paper summarizes the experiences with the operation of the piNAV GPS receiver in a 1U unstabilized CubeSat operated on LEO orbit.
piNAV L1 is a GPS receiver developed by an author for small satellite missions.
The receiver is equipped with the 15 GPS L1 C/A channels and acquisition accelerator that shortens the cold start of the receiver on LEO to 65 s.
The typical power consumption is 120 mW.
Lucky-7 is a private 1U technological CubeSat with power budget 1 W that operates on the quasisynchronous polar orbit at altitude 520 km.
One of its scientific missions is to test the operation of GPS.
The space experiments proved the successful operation of the GPS receiver.
The position information was available for approximately 80% of the time, where the position outage was caused by a satellite rotation and relatively long navigation signal reacquisition.
The experimental data proved that the position availability can be improved by a higher-performance signal acquisition engine.
