CUAV C-RTK 9Ps Positioning Module | High Precision GPS RTK GNSS Pixhawk

C-RTK 9Ps Positioning Module is a centimeter-level GNSS module. Using two c-RTK modules, one installed on the base and the other installed on the UAV, a real-time GNSS system is designed. By using dual GPS on the plane, you can replace the compass and have a dual GPS yaw. This is desirable due to the error of the compass coming from electromagnetic interferences, suitable for environments with high noise. Compatible with open-source autopilots like PX4 or Ardupilot, this RTK module is an ideal choice for aerial performance and agricultural applications. You can have high-precision take-off, landing, and missions.

A ublox F9P module is used inside to support multiple frequencies as well as the reception from different satellite systems — GPS, Beidou, Glonass, and Galileo.
