The Satlab Polaris ADS-B is a fully self-contained software-defined radio receiver for 1090 MHz ADS-B messages, with integrated demodulator and storage.
This versatile SDR offers excellent performance given the typical size, weight and power constraints of a CubeSat - or as an additional payload on larger LEO satellites.
The Polaris ADS-B receiver is based on Satlabs second generation SDR platform, based on the in-orbit experience gained from the QubeAIS receiver, which has flown on several missions since 2013.
