GNSS heading receiver designed for easy integration into UAS
The AsteRx-m2a UAS is specifically designed for straightforward integration into UAS applications providing centimetre-level RTK positioning and accurate heading for just over 1 W. It features standard connections to Pixhawk and ArduPilot as well as event marker inputs to accurately time stamp camera shutter events.
No need for Ground Control Points
The AsteRx-m2a 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 either Ground Control Points or a real-time datalink.
- Multi-constellation, multi-frequency all-in-view satellite tracking
- Centimetre-level (RTK) position accuracy with or without a real-time datalink
- Heading output for orientation or INS integrations
- AIM+ anti-jamming and monitoring system + advanced GNSS+ algorithms
- Camera shutter synchronisation
- Plug compatible with ArduPilot/Pixhawk
Designed for UAS
The AsteRx-m2a UAS is designed for easy integration into any system. Standard connectors connect directly to your autopilot (e.g. Pixhawk) and the wide 6-30 V input power range allows powering the receiver directly from the UAS power bus. Event markers can accurately synchronise a camera shutter with GNSS time. The command interface is fully documented and an SDK is provided to help create professional custom applications.
Ultra-low power design
The AsteRx-m2a UAS provides RTK positioning at the lowest power consumption of any comparable device on the market. This means lower heat dissipation, simpler integrations and longer operation on a single battery charge.
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.
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.
Intuitive web user interface
With your high-precision GPS reference receiver comes an intuitive web user interface for easy operation and monitoring allowing you to control the receiver from any mobile device or computer. The web interface also uses easy-to-read quality indicators ideal to monitor the receiver operation during the job at hand.
