Septentrio has announced the launch of the AsteRx-m2 and AsteRx-m2 UAS, the company’s newest OEM GNSS receiver boards. The credit-card sized boards offer all-in-view multi-frequency, multi-constellation tracking and centimetre-level RTK position accuracy with extremely low power. Additionally, the AsteRx-m2 and the AsteRx-m2 UAS can receive TerraStar satellite-based correction signals for PPP positioning.
The AsteRx-m2 and the AsteRx-m2 UAS feature Septentrio’s AIM+ advanced interference mitigation system, which can suppress a wide variety of interferers, from simple continuous narrowband signals to the most 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 unmanned aircraft systems (UAS), makes interference mitigation a vital element in any UAS GNSS system.
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 synchronise 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.
“The market demands increasingly accurate and reliable GNSS positioning systems for inspection, mapping and aerial survey” stated Gustavo Lopez, Product Manager at Septentrio. He continued: “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.”
