Multi-constellation GNSS receiver for applications requiring centimeter position accuracy, (Dual Antenna, multi-frequency GPS/GLONASS/GALILEO/BEIDOU/IRNSS,  including SBAS, DGNSS rover, SECORX-D or -C (PPP), RTK rover. (excl. SECORX subscription))

AsteRx4 OEM  board is delivered with cohomprehensive manuals and RxTools a suite of configuration, conversion and logging tools.


The AsteRx4 is the most advanced multi-constellation dual antenna receiver from Septentrio. Its triple frequency engine can track all Global Navigation Satellite System (GNSS) constellations - GPS, GLONASS, Galileo, BeiDou, IRNSS and QZSS – on both antennas. It supports current and future signals as they become available – guaranteeing you reliable and accurate GNSS positioning into the future.

Interference Robustness 

The AsteRx-m2 UAS features AIM+, the most advanced onboard interference mitigation technology on the market. It can suppress the widest variety of interferers, from simple continuous narrowband signals to the most complex wideband and pulsed jammers. The RF spectrum can be viewed in real-time in both time and frequency domains. .
