CUAV C-RTK 9Ps Positioning Module | High Precision GPS RTK GNSS Pixhawk
The CUAV C-RTK 9Ps Positioning Module is an advanced GNSS unit offering centimeter-level precision. By deploying two C-RTK modules—one on the base station and the other on the UAV—an effective real-time GNSS system is established. This setup allows for dual GPS integration on the aircraft, enabling the replacement of the compass and providing dual GPS yaw. This feature is particularly advantageous in environments prone to electromagnetic interference, offering superior performance in high-noise conditions.
Compatible with open-source autopilots such as PX4 or Ardupilot, this RTK module is well-suited for a wide range of aerial operations and agricultural applications. Its capabilities include high-precision take-off, landing, and mission execution.
Internally, the module incorporates a ublox F9P chipset, enabling support for multiple frequencies and reception from various satellite systems including GPS, Beidou, Glonass, and Galileo. This comprehensive satellite coverage ensures robust and reliable positioning accuracy across diverse operating environments.
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.

Features:
Multi-star Multi-Frequency High- Precision Positioning
Ultra-fast positioning
Dual RTK for yaw, Adapts to a complex environment
Fast switch between sky and rover unit
CUAV C-RTK 9Ps Positioning Module adopts the same design as the two units (sky unit and rover unit), and the two units use the same firmware. You only need to load different configuration parameters to complete the fast switching.
The CUAV C-RTK 9Ps Positioning Module can support all versions of CUAV Flight Controllers.
