Ground-based differential base stations are specialized ground‑based reference devices that can provide centimeter‑level high‑accuracy positioning.

Using RTK carrier-phase differential technology, satellite positioning errors are corrected in real time, enabling high-precision positioning and orientation control for applications such as precise drone hovering and accurate waypoint navigation.

Features And Advantages

FEATURES AND ADVANTAGES
  • Centimeter-level high-precision positioning and orientation

    By employing RTK real-time kinematic differential technology, satellite positioning errors can be effectively eliminated.

  • Compatible with all constellation satellites

    Supports full-system, full-frequency satellite signal reception.

  • Rich external interface resources

    Supports multiple data transmission interfaces, including serial port, Ethernet, CAN, and USB.

  • Strengthen structural and waterproofing design.

    The structure is fabricated from thickened aluminum alloy, employs a flange-mounted waterproof connector, and incorporates a waterproof design for the open‑type mechanical interface.

  • Convenient App

    The system is built as an integrated unit using modular components, enabling rapid assembly and deployment. It employs quick‑connect, quick‑disconnect connectors to enhance the user experience.
