CUAV C-RTK 9Ps Centimeter-Level GNSS Module Brief:
The C-RTK 9Ps is a multi-star multi-frequency GNSS system. It also supports dual GPS for yaw, which can replace a sensor, and is useful for complex magnetic environments, such as close to power lines. It is a very cost-effective centimeter-level RTK module compatible with PX4/ArduPilot open-source controllers. It is an ideal choice for Unmanned Systems mapping, agricultural applications, centimeter-level takeoff and landing, ship takeoff and landing, and other applications requiring real-time centimeter-level navigation.
C-RTK 9Ps GNSS Feature:
- Multi-satellite multi-frequency receiver
- Centimeter-level positioning
- Dual RTK direction-finding
- Dual-end switchover design

C-RTK 9Ps GNSS Description：
Multi-star Multi-Frequency Centimeter-Level Positioning
Built-in u-blox F9P multi-star multi-frequency satellite receiver, four GPS, Beidou, GLONASS, GALILEO four satellite systems, and supports the simultaneous reception of four satellite systems, positioning accuracy ≤rtk0.01m + 1ppm CEP.
Fast positioning, No waiting
Through the multi-satellite and multi-frequency receiver, and combined with the advanced RTK algorithm, the base station can complete convergence and send differential data to the rover unit in half a minute to achieve centimeter-level positioning
Dual RTK for yaw Adapt to complex environment
Dual C-RTK 9Ps can estimate yaw. Replacing the electronic compass in Unmanned Systems; The Unmanned Systems can work stably in a complex electromagnetic environment, such as electric power inspection
Fast switch between sky androver unit
The C-RTK 9Ps 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
