Description
The HBEV11 is a full-frequency integrated RTK GNSS receiver built on the Septentrio mosaic-G5 P3 module, housed in a compact 85 × 10 mm low-profile antenna form factor. It combines the GNSS receiver, LNA, SAW filtering, full-band patch antenna, backup battery, and communication interfaces in a single module — delivering 0.6 cm RTK accuracy at approximately 0.44 W for UAVs, robots, and space-constrained autonomous platforms.
Key Features
- Septentrio mosaic-G5 P3 — 789 hardware channels, full multi-constellation multi-frequency
- 0.6 cm + 0.5 ppm RTK horizontal accuracy; 0.03° heading at 5 m baseline (P3H option)
- Integrated LNA, SAW filter, full-band patch antenna, backup battery in one module
- AIM+ active interference & spoofing mitigation · APME+ multipath suppression
- LOCK+ vibration-resistant tracking · IONO+ ionospheric protection · RAIM+ integrity monitoring
- Ultra-low power: ~0.44 W at 3.3 V — ideal for battery-powered and weight-critical UAV platforms
- UART / USB / RS232 interfaces · NMEA 0183 / SBF / RTCM v3.x protocols
- CE / FCC / RoHS / WEEE / ISED certified
