Description The HB6 is a compact multi-band RTK GNSS P-Box receiver powered by the Septentrio mosaic-X5 engine, delivering 0.6 cm RTK accuracy with 448 hardware channels across all major constellations and frequencies. At just 68.4 × 41.8 × 13.5 mm and 45 g, it integrates a TCXO, LNA, and 32 GB TF card slot — supporting single-antenna positioning or dual-antenna heading output via optional mosaic-H configuration. Designed for UAVs, autonomous robots, precision control, and unmanned systems.
