HBEV322 / HBEV322H Compact RTK GNSS Receiver — Septentrio mosaic-G5 P3H
The HBEV322 / HBEV322H is a 14 g cylindrical RTK GNSS receiver built on the Septentrio mosaic-G5 P3H. Measuring φ44 × 40.6 mm, it delivers 0.6 cm RTK accuracy and 0.15° dual-antenna heading, with an integrated QMC5883L compass over I²C — all via an 8-pin GH1.25 mm connector. Ideal for UAVs, AGVs, and compact robotic platforms where mass and size are critical constraints.
Description
14 g Cylindrical RTK GNSS Receiver with Integrated Compass
The HBEV322 / HBEV322H packs a complete RTK GNSS solution into a φ44 × 40.6 mm cylindrical housing weighing just 14 g. Powered by the Septentrio mosaic-G5 P3H, it delivers centimetre-level positioning, dual-antenna heading output, and magnetic heading via an on-board QMC5883L compass (I²C) — all accessible through a single 8-pin GH1.25 mm interface.
