Septentrio debuted the AsteRx-m2a and AsteRx-m2a UAS GNSS OEM engines at Commercial UAV 2017, held Oct. 24-26 in Las Vegas. The two new OEM boards provide precise and reliable multi-frequency, all-in-view real-time kinematic (RTK) positioning and heading — along with interference technology — with low power consumption, the company said. Both boards are 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. The AsteRx-m2a board by Septentrio. Photo: Septentrio 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 and attitude to any space-constrained application. According to the company, both receivers are designed to serve as core components in any multi-sensor application. The 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. The board can be powered directly from the vehicle power bus via its wide-range input. The AsteRx-m2 UAS board by Septentrio. Photo: Septentrio 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. “We’ve taken the hugely successful AsteRx-m2 and added a second antenna input for high-precision GNSS heading,” said Gustavo Lopez, OEM product manager at Septentrio. “No need to manoeuvre around in a figure of ‘8’ trying to initialise 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.” Septentrio is located at booth 206 of Commercial UAV Expo 2017.
