Photo: Septentrio GNSS receiver manufacturer Septentrio is introducing its AsteRx SB at two industry shows: Expomin in Santiago, Chile (April 23-27), and Intermat in Paris, France. According to the company, the AsteRx SB delivers Septentrio’s quad-constellation real-time kinematic (RTK) positioning in a low-power, IP68 compliant housing. Built around the AsteRx-m2 GNSS receiver engine, the AsteRx SB features Wi-Fi, Bluetooth, USB, Ethernet and serial connectivity. Septentrio’s GNSS+ suite of positioning algorithms converts difficult environments into good positioning: LOCK+ technology to maintain tracking during heavy vibration, APME+ to combat multipath, and IONO+ technology to ensure position accuracy during periods of elevated ionospheric activity. The AsteRx SB also features the AIM+ interference mitigation and monitoring system, which can suppress the widest variety of interferers, from simple continuous narrowband signals to the most complex wideband and pulsed jammers. Key benefits for users: Quad-constellation, multi-frequency, all-in-view RTK receiver Robust and compact IP68 weatherproof housing AIM+ interference monitoring and mitigation system L-band PPP, RTK, scalable accuracy High-update rate, low-latency positioning Base and rover operation Bluetooth, Wi-Fi, Ethernet, serial and USB communications Whether exposed to the elements or inside a vehicle cab, operating alone or as a core component of a sensor-fusion system, the AsteRx SB is straight-forward to set up and integrate into any new or existing application. Using Wi-Fi or micro USB, the AsteRx SB can be configured and monitored using any device with a web browser. “We believe the AsteRx SB is the best all-rounder on the market today. We’ve produced a small and low-power device with zero compromise on performance,” said Gustavo Lopez, product manager at Septentrio. “From machine control to sensor-fusion applications, manned or unmanned, the compact size and low power of the AsteRx SB along with its range of communications options make it ideal for any project requiring reliable high-precision positioning.” At Intermat in Paris, Septentrio will exhibit at Booth 6H-041 and at Expomin in Santiago, Chile, at Booth 1K-30.
