Overview
The Beitian UM982/UM980/ZED-F9P (B9) RTK GNSS positioning board is a high-precision positioning and orientation module designed for vehicle and UAV integration. The series supports multi-constellation operation (BDS/GPS/GLONASS/Galileo/QZSS; some variants also list SBAS) and is available in multiple board/module options (BT-982 / BT-980 / BT-F9P models) to match different interfaces and installation sizes.
Key Features
- Full system, full-frequency GNSS positioning and orientation module (model-dependent)
- Adaptive anti-interference capability: suppresses wide/narrow band and continuous wave interference signals
- Multi-field applications: driving test/training, unmanned aerial vehicles, agricultural machinery navigation, robots, intelligent driving, and other high-precision positioning scenarios
- System support shown: Windows, Linux, CE
- Reference station and mobile station switching shown (base/rover use)

Details

Choose the board version that matches your interface needs and installation size, with core specs compared side by side.

Multiple board layouts are available for vehicle and UAV integrations, including options designed for positioning plus heading.

Full-constellation tracking supports reliable RTK operation across more satellites and frequency bands (model dependent).

Pin definitions and electrical characteristics help streamline wiring for UART and other common integration interfaces.

Status LEDs and connector pinouts make it easier to validate power, RTK fix, and data output during setup.

For heading applications, dual-antenna placement enables orientation output while RTK corrections deliver centimeter-level positioning.

Flexible base/rover deployment supports either radio links or wired correction delivery, depending on your system design.

Adaptive anti-interference design improves stability in complex RF environments across UAV, robotics, and vehicle use cases.

Broad OS support and base/rover switching options fit both development testing and field deployment workflows.


Kits include the selected module plus matching cables and locking connectors to simplify initial installation.
