AsteRx-m2 UAS

The AsteRx-m2 UAS is a GNSS receiver especially designed for straightforward integration into UAS applications providing ultra-low power, centimeter-level RTK positioning. It features standard connections to Pixhawk and Ardupilot and a wide range 6-30 V power input as well as an event marker input to accurately time stamp camera shutter events.

Designed for UAS

The AsteRx-m2 UAS is designed and built for easy integration into any system. Standard connectors directly connect to your autopilot (e.g. Pixhawk) and the wide 6-30 V input power range allows you to use the power directly from the vehicle power bus.

No need for Ground Control Points

The AsteRx-m2 UAS works seamlessly with GeoTagZ software and its SDK library for PPK (Post Processed Kinematic) offline processing. This gives RTK accuracy without the need for Ground Control points or a real-time datalink.

Ultra-low power design

The AsteRx-m2 UAS provides RTK positioning at the lowest power consumption of any comparable device on the market.

The GNSS+ toolkit - converting bad environments into good positioning

Activity in the ionosphere is a problem for GNSS signals, from loss of RTK fix to total loss of signal lock. Having honed our skills, supporting applications in the most iono-active areas on Earth,  the result is IONO+: the most advanced protection against ionospheric disturbances to GNSS signals on any receiver.

Metal and large nearby structures can reflect GNSS signals and produce multipath. The APME+ system effectively disentangles direct and reflected signals enhancing both position and measurement quality. APME+ is bias free and, in line with Septentrio’s commitment to maximum configurability, can be disabled.

Advanced Receiver Autonomous Integrity Monitoring (RAIM+) comprises fault detection mechanisms of the receiver at all the levels including the generation of measurements, quality control and navigation algorithms. Detected faulty measurements, which are typically caused by high multipath or active ionosphere, are removed from the solution.

Mechanical vibrations or shocks caused by rough terrain can wreak havoc with satellite tracking. LOCK+ automatically adjusts the parameters of the high-precision GPS / GNSS receiver board so you never lose position.

AIM+ anti-jamming and RF spectrum monitoring system

All Septentrio high-precision GPS/GNSS receivers feature AIM+, the most advanced onboard  radio frequency interference (RFI) monitoring and 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 built-in protection against intentional and unintentional jamming and spoofing uses a sophisticated system of sampling and mitigation mechanisms. The RF spectrum can be viewed in real-time in both time and frequency domains.
