The AsteRx-m3 Pro from Septentrio is a Multi-Band, Multi-Constellation GNSS Receiver which is specifically designed for the needs of mass-market applications like robotics and autonomous systems. This high precision GNSS receiver delivers reliable and robust centimeter-level accuracy (RTK) in challenging environments with both single and dual antenna modes. It has a TTFF cold start under 45s, TTFF warm start under 20s, and provides tracking sensitivity of 20 dB-Hz and acquisition sensitivity of 33 dB-Hz. This receiver requires a DC supply from 3-5.5 V and consumes 1000 mW of power. It has a latency of less than 10 ms, and supports UART, Ethernet, USB, GPIO, TCP/IP and UDP interfaces.
The AsteRx-m3 Pro features AIM+ for advanced interference monitoring, anti-jamming and anti-spoofing, LOCK+ for robust tracking during high vibrations and shocks, APME+ for multipath mitigation to disentangle direct signal and those reflected from nearby structures, IONO+ for advanced protection against ionospheric disturbances, and RAIM+ for receiver autonomous integrity monitoring. It is designed to deliver reliable positions even when GNSS signals are disturbed or when the receiver is subject to shocks and vibrations.
This GNSS Receiver is available in a compact surface-mount package that measures 47.5 x 70 x 9.32 mm with 2 MMCX antenna connectors and is ideal for the rover and kinematic applications where reliable and high-accuracy positioning is needed.
