Septentrio has released two new GNSS receivers, the AsteRx-m2 and AsteRx-m2 UAS. They are designed to offer unmatched interference mitigation technology on ultra-low-power.

“The market demands increasingly accurate and reliable GNSS positioning systems for inspection, mapping and aerial survey,” says Gustavo Lopez, product manager at Septentrio. “Septentrio’s answer is the AsteRx-m2 and the AsteRx-m2 UAS, offering multi-frequency and multi-constellation tracking, as well as robust interference protection all for the lowest power on the market.”

The credit card sized AsteRx-m2 and the AsteRx-m2 UAS offer all-in-view multi-frequency, multi-constellation tracking and centimeter-level RTK position accuracy for what Septentrio touts as the lowest power of any comparable receiver. Additionally, the AsteRx-m2 and the AsteRx-m2 UAS can receive TerraStar satellite-based correction signals for PPP positioning. 

The new OEM boards feature Septentrio’s AIM+ interference mitigation system. It can suppress a wide variety of interferers, from simple continuous narrowband signals to complex wideband and pulsed jammers. The 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 GNSS system, Septentrio says.

The AsteRx-m2 UAS is designed specifically for unmanned systems. It brings plug-and-play compatibility for autopilot software such as ArduPilot and Pixhawk and event markers can accurately synchronize a camera shutter with GNSS time. The board can be directly powered from the vehicle power bus via its wide-range power input. The AsteRx-m2 UAS works seamlessly with GeoTagZ software and its SDK library for RPK (ReProcessed Kinematic) offline processing to provide RTK accuracy without the need for ground control points or a real-time datalink.
