HBEV322 / HBEV322H Compact RTK GNSS Receiver — Septentrio mosaic-G5
HBEV322 / HBEV322H is a compact, lightweight all-constellation RTK GNSS receiver with integrated QMC5883L compass, powered by the Septentrio mosaic-G5 P3H module. At just 14 g and φ44 × 40.6 mm, it delivers centimetre-level RTK positioning and 0.15° dual-antenna heading for UAV, AGV, ADAS, and robotic platforms.
Description
Compact RTK GNSS Receiver with Integrated Compass
The HBEV322 / HBEV322H is a compact, high-performance RTK GNSS receiver based on the Septentrio mosaic-G5 P3H module. It receives multi-constellation, multi-frequency signals and provides centimetre-level positioning, heading, speed, and timing output — all in a cylindrical housing weighing just 14 g. The integrated QMC5883L compass adds magnetic heading support via I²C, making it ideal for compact navigation platforms where a dual-antenna baseline is not always possible.
