Septentrio has announced the release of the AsteRx-m2a and AsteRx-m2a drone GNSS OEM engines. The two new OEM boards bring the latest in precise and reliable multi-frequency, all-in-view RTK positioning and heading to the market.

“We’ve taken the hugely successful AsteRx-m2 and added a second antenna input for high-precision GNSS heading. No need to maneuver around in a figure of eight trying to initialize INS heading or find space or additional power for a separate INS module. Now, all you need is a second antenna and you’re good to go,” says Gustavo Lopez, OEM product manager at Septentrio.

The AsteRx-m2a and AsteRx-m2a UAS are both smaller than a credit card and feature Septentrio’s AIM+ interference mitigation and monitoring system. AIM+ can suppress a wide variety of interferers, from simple continuous narrowband signals to the most complex wideband and pulsed jammers. Increasing levels of radio-frequency pollution coupled with the intrinsic danger of self-interference in compact systems, such as UAS, makes interference mitigation a vital element in any UAS system that uses GNSS positioning. 

Both boards are designed to bring high-precision positioning to any space-constrained application. The focus on ease-of-integration along with high-update rate, low-latency output makes both receivers core components in any multi-sensor application.

AsteRx-m2a UAS is aimed specifically at unmanned applications bringing plug-and-play compatibility for autopilot systems such as ArduPilot and Pixhawk. Event markers accurately synchronize camera shutter events with GNSS time and the board can be powered directly from the vehicle power bus via its wide-range input. The AsteRx-m2a UAS works seamlessly with GeoTagZ Software providing offline re-processed RTK accuracy without the need for either Ground Control Points or a real-time datalink.
