This 4-channel AIS receiver, Polaris, is designed by Nano Avionics partner Satlab. Polaris is a fully self-contained software defined radio receiver for the maritime VHF band with integrated demodulators for receiving standard and long range AIS messages. This versatile SDR offers excellent performance given the typical size, weight, and power constraints of CubeSat, or as an additional payload for larger LEO satellites. Polaris is Satlab's second generation satellite AIS receiver, based on in-orbit experience gained from Qube AIS receivers flying on several missions since 2013.
