HB50H Multi-Frequency GNSS Heading Receiver — 20 Hz, Septentrio Mosaic H-series
Multi-frequency GNSS receiver with dual-antenna heading — powered by Septentrio Mosaic H-series. 0.15° heading, 20 Hz RTK, AIM+ Advanced, only 50 g.
Description
The HB50H is a multi-frequency GNSS receiver with dual-antenna heading — powered by the Septentrio Mosaic H-series module. Designed for applications requiring precise orientation, it delivers true dual-antenna heading (accuracy 0.15° @ 1 m baseline) in a compact, low-power form factor. Ideal for UAV navigation, unmanned systems (USV), precision control, robotics, and construction applications.
Key Features
- Septentrio Mosaic H-series Inside — AIM+ Advanced anti-jamming · APME+ multipath suppression · IONO+ scintillation protection · OSNMA anti-spoofing · LOCK+ robust tracking · RAIM+ integrity monitoring
- Dual-antenna heading: 0.15° orientation + 0.25° pitch/roll @ 1 m baseline; 0.03° / 0.05° @ 5 m baseline
- 20 Hz navigation update rate; RTK accuracy: 0.6 cm + 0.5 ppm H / 1 cm + 1 ppm V
- 5-constellation, multi-frequency GNSS: GPS, BDS, GLONASS, Galileo, QZSS
- Ultra-low power: 0.60 W typical (with heading) — ideal for battery-powered systems
- Compact: 5.9 × 4.4 × 1.2 cm · only 50 g
- 2 × UART + USB Micro + 2 × GPIO + 2 × Event + 2 × PPS + SD/MMC
HB50H vs HB56H: Both use the identical Septentrio Mosaic H-series module with the same heading performance, RTK accuracy, size (5.9 × 4.4 × 1.2 cm), weight (50 g), and power consumption (0.60 W). The HB56H offers a different connector pinout for alternative integration layouts.
Don’t need heading? The HB50 / HB56 (Septentrio Mosaic X5) offer a faster 100 Hz update rate — ideal for high-dynamic tracking without orientation.
