HB56H Multi-Frequency GNSS Heading Receiver — 20 Hz, Septentrio Mosaic H-series (Variant)
Multi-frequency GNSS heading receiver with alternative connector — powered by Septentrio Mosaic H-series. 0.15° heading, 20 Hz RTK, AIM+ Advanced, 50 g.
Description
The HB56H is a multi-frequency GNSS receiver with dual-antenna heading — powered by the Septentrio Mosaic H-series module. It shares the same core heading engine as the HB50H but with an alternative connector configuration for flexible system integration. 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
- Ultra-low power: 0.60 W typical (with heading)
- 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 (0.15° @ 1 m), 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 to suit alternative cabling or mounting requirements — choose the variant that best matches your interface layout.
Don’t need heading? The HB50 / HB56 (Septentrio Mosaic X5) offer a faster 100 Hz update rate — ideal for high-dynamic tracking without orientation.
