C-RTK2 HP Positioning and Heading Modul
C-RTK2 HP is a full-constellation satellite multi-frequency positioning and heading module independently developed by CUAV. Integrated dual-antenna heading system, one module can realize GPS heading. It makes it easy for UAVs to have application scenarios in complex magnetic field environments such as power line inspections and metal ore inspections. It supports full-system full-band GNSS receivers and provides powerful satellite positioning capabilities. In RTK state, you can get 50+ satellite positioning services and centimeter-level high-precision positioning. C-RTK2 HP also supports UART and Dronecan dual communication interfaces. Dronecan can guarantee higher security and stronger anti-interference for data communication, while UART interface can guarantee compatibility with other non-CAN devices.
C-RTK2 HP is ideal for high precision positioning and haeding, especially for unmanned system applications.
[!NOTE] C-RTK2 HP supports ArduPilot 4.4.0 and above firmware
