HB6 GNSS Receiver | Septentrio mosaic-X5 or mosaic-H | Single-/Dual-Antenna RTK
The HB6 is a compact multi-band, multi-constellation P-Box terminal GNSS receiver supporting both single-antenna positioning via the Septentrio mosaic-X5 and dual-antenna heading via the Septentrio mosaic-H. With 448 hardware channels, 100 Hz update rate, <10 ms latency and 0.6 cm + 0.5 ppm RTK accuracy, it is designed for UAVs, drones, autonomous vehicles and unmanned systems. AIM+ anti-interference, APME+, IONO+, LOCK+ and RAIM+ protection ensure reliable high-precision positioning in demanding environments.
Description
The HB6 is a compact multi-band, multi-constellation P-Box terminal GNSS receiver offering two configurations: single-antenna positioning with the Septentrio mosaic-X5, or dual-antenna heading with the Septentrio mosaic-H. With 448 hardware channels, 100 Hz positioning updates and ultra-low <10 ms latency, it supports UAVs, autonomous robots, driverless vehicles, plant-protection drones and unmanned ships. Septentrio’s AIM+ anti-interference, APME+ multipath mitigation, IONO+ scintillation suppression and LOCK+ robust tracking deliver reliable performance in complex RF environments. The receiver also includes interference indication, interference mitigation and spectrum measurement functions.
