The Satlab Polaris receiver is a fully self-contained, 4-channel, software-defined radio receiver for the maritime VHF band, with integrated demodulators for reception of standard and long-range AIS messages. 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.

Polaris is Satlab’s second generation Satellite-AIS receiver, based on the in-orbit experience gained from the QubeAIS receiver which has flown on several missions since 2013.
