Key highlights
The Satlab Polaris LoRa is a fully self-contained software-defined radio receiver for 868 MHz ISM band LoRa 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 LoRa 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.
