YX-OS27 NavCore UM982 RTK GNSS Board

The NavCore UM982 RTK GNSS Board is a flagship positioning and orientation solution for professional drones, robotics, and high‑precision navigation. Built on the latest Beidou‑3 technology, it tracks significantly more satellites than the UM482 – thanks to its newest firmware – ensuring faster lock times, higher accuracy, and stable heading even in challenging environments.

Whether you need single‑antenna positioning or dual‑antenna orientation, rover or base station operation, the UM982 delivers. Two independent serial ports let you connect a flight controller (Pixhawk), 4G module, or external MCU simultaneously. A Type‑C port enables direct PC configuration.

Key Benefits

• More satellites, better performance: Latest firmware tracks all visible Beidou‑3, GPS, GLONASS, and Galileo satellites – outperforming UM482 in accuracy, orientation stability, and interference rejection.
• Dual‑antenna orientation: Provides precise heading (yaw) for drones, vehicles, vessels, and robots where compasses fail.
• Rover or base mode: Use as a moving rover or set as a stationary base station for RTK corrections.
• Two UART ports (9600–921600 baud): Connect to Pixhawk flight controller, 4G module, and an MCU at the same time.
• Type‑C configuration port: Plug directly into a PC – no extra adapter needed.
• Antenna short‑circuit protection: Safeguards the module against accidental antenna shorts.
• Free 3D case model: Download and 3D‑print your own enclosure.
