CUAV C-RTK 9Ps Positioning Module

CUAV C-RTK 9Ps 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 gps 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, Galileo.

Due to using multiple satellites and multiple frequencies, and with the help of advanced RTK algorithms, the position of the base station converges and provides centimeter-level differential data in less than half a minute. The update rate of the RTK algorithm is at 20Hz.

The base and rover units are the same modules with different configuration parameters and different antennas. That just makes it easy to use them in place of each other by just changing a few parameters. However, the antenna used on the rove has a 2dBi gain, while the base station uses a 5dBi gain antenna. The modules are only 30g, and can work in harsh environments and temperatures from –40°C to +85°C.
