Does SSN develop attitude receivers?
Septentrio’s PolaRx2@ multi-antenna receiver is a single-board receiver that can be connected to up to 3 antennas: 1 dual-frequency antennas and 2 single-frequency antennas. The combination of measurements from the three antennas placed on a rigid vehicle allows the receiver to calculate besides position, velocity also the attitude of the vehicle. The attitude is expressed in Euler angles (heading, pitch, roll), which are the angles between the vehicle platform and the local-level navigation frame (ENU).
