GW16171 Precision GNSS M.2 Card
Overview
Industrial GNSS M.2 Card with Septentrio Mosaic-G5 for Centimeter-Level Accuracy
The Gateworks GW16171 is a rugged, industrial-grade GNSS M.2 card featuring the Septentrio mosaic-G5 multi-frequency receiver. Designed for autonomous systems, robotics, drones and outdoor asset tracking, it delivers centimeter-level RTK positioning and interference mitigation in a compact, low-power form factor. The GW16171 seamlessly integrates with Gateworks SBCs to enable high-accuracy GNSS for edge applications in even the most challenging environments. The Septentrio Mosaic-G5 receiver module supports up to 789 hardware channels, including GPS, GLONASS, Beidou, Galileo, QZSS, Navic, SBAS, L-band and 5 constellation RTK (base and rover).
