AIS Receiver

Basic Price € 20,000

This 4-channel AIS Receiver “Polaris” is designed by NanoAvionics’ partner Satlab. Polaris is a fully self-contained 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.
