Polaris AIS Maritime VHF Receiver

The Satlab Polaris AIS is a fully self-contained software-defined radio receiver for the maritime VHF band, with integrated demodulators for the 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.
