Septentrio AsteRx3 HDC

The AsteRx3 HDC multi-frequency GNSS receiver by Septentrio Satellite Navigation can track GPS, GLONASS, Galileo, SBAS and COMPASS signals. It is equipped with a robust OEM receiver engine and is designed for applications that require high performance multi-frequency applications. The AsteRx3 is capable of delivering centimeter-level positioning.




The AsteRx3 receiver features an A Posteriori Multipath Estimator, which offers effective multipath mitigation and reduces signal interferences. This results in improved accuracy of the received data. The receiver also utilizes other GNSS+ technology, including Lock+, RTK+, AIM+ and ATrack+, to deliver highly reliable and accurate performance, even in harsh environments.

Moreover, the AsteRx3 HDC is easy to integrate. Users can easily upgrade from a dual-frequency application to multi-frequency one, as the AsteRx3 is fully compatible with the AsteRx2 and AsteRx2e receivers. Furthermore, the AsteRx3 is available as an integrated unit or OEM board.
