AsteRx-i D UAS

GNSS/INS positioning and attitude receiver for easy UAS integration


The AsteRx-i D UAS is a GNSS+INS receiver specifically designed for straightforward integration into Unmanned Aerial Systems (UAS).  It provides centimeter-level RTK positioning and 3D attitude. It features a 44 pin connector compatible with 3rd party integrations, as well as event marker inputs to accurately time stamp camera shutter events.

The GNSS+ Technologies - converting bad environments into good positioning

Mechanical vibrations or shocks caused by taking-off or landing can wreak havoc with satellite tracking. LOCK+ automatically adjusts the parameters of the AsteRx-i D UAS receiver so you never lose position, this combined with the vibration resilience of the on board IMU delivers a fully reliable GNSS+INS.

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 Advanced Multipath Mitigation Technology APME+ 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.

AIM+ anti-jamming and RF spectrum monitoring system


The AsteRx-i D UAS  features AIM+: advanced Interference Monitoring and mitigation, offers built-in protection against intentional and unintentional jamming and spoofing using a sophisticated system of sampling and mitigation mechanisms. In robotic devices neighboring electronics can produce RF radiation which interferes with GNSS signals. AIM+ offers protection against such interference resulting in faster set-up time and robust continuous operation.

Intuitive web user interface

The AsteRx-i D UAS includes 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.
