Description
The HB6 Pro is a compact multi-band RTK GNSS box receiver with integrated 4G LTE connectivity, powered by the Septentrio mosaic-X5 engine. It delivers centimetre-level RTK accuracy with direct NTRIP corrections over cellular — eliminating the need for external modems on UAVs, autonomous vehicles, and robotic platforms.
Key Features
- Septentrio mosaic-X5 — 448 hardware channels, full multi-constellation multi-frequency tracking
- Integrated 4G LTE for direct NTRIP RTK correction over cellular networks
- 0.6 cm + 0.5 ppm RTK horizontal accuracy; 7 s typical initialization
- AIM+ active interference & spoofing mitigation · APME+ multipath suppression
- LOCK+ vibration-resistant tracking · IONO+ ionospheric protection · RAIM+ integrity monitoring
- Galileo OSNMA authentication — hardware-level spoofing detection
- Dual-antenna heading: 0.03° @ 5 m baseline; 100 Hz update rate; <10 ms latency
- Built-in TCXO, LNA, 32 GB TF card slot; no external modem required
