HB50 Multi-Frequency GNSS Receiver — 100 Hz, Septentrio Mosaic X5
Multi-frequency GNSS receiver powered by Septentrio Mosaic X5 — 100 Hz RTK, AIM+ anti-jamming, 0.6 cm accuracy, compact 60 g design for UAVs, AGVs and robotics.
Description
The HB50 is a multi-frequency GNSS receiver powered by a Septentrio Mosaic X5 module — designed for applications that require high-speed positioning without heading. With a 100 Hz update rate and ultra-low latency, it excels in dynamic environments such as UAV navigation, autonomous ground vehicles (AGV), ADAS testing, and robotics.
Key Features
- Septentrio Mosaic X5 Inside — AIM+ anti-jamming · APME+ multipath suppression · IONO+ scintillation protection · OSNMA anti-spoofing · LOCK+ robust tracking · RAIM+ integrity monitoring
- 100 Hz navigation and measurement update rate for high-dynamic applications
- RTK accuracy: 0.6 cm + 0.5 ppm H / 1 cm + 1 ppm V; 7 s initialization
- 5-constellation, multi-frequency GNSS: GPS, BDS, GLONASS, Galileo, QZSS, NavIC, SBAS
- 2 × UART + USB Type-C + SD/MMC + event marker + PPS output
- Compact board: 5.1 × 4.9 cm · weight: 60 g
- Stable tracking during high-frequency vibration and fast movement
Comparison: The HB50 uses the same core Septentrio Mosaic X5 module as the HB56. Both share identical positioning performance, size, and interfaces. The difference is in connector configuration — choose the variant that best matches your integration layout.
Need heading/orientation? See the HB50H (Septentrio Mosaic H-series, dual-antenna heading, smaller form factor) or HB56H.
