ADS-B Receiver

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 built on Satlab’s second generation SDR platform, based on the in-orbit experience gained from the QubeAIS receiver, which has flown on several missions since 2013.

The Polaris ADS-B is part of our Polaris SDR product line that has demonstrated reliable flight heritage since 2019, with over 100 units successfully delivered to customers around the world for a multitude of space missions. With a TRL of 9, it is fully qualified and operational in its intended environment.
