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

The primary advantage is centimeter-level Real-Time Kinematic (RTK) positioning accuracy, achieved by using one module as a base station to correct signals received by a rover module on the drone. This eliminates common GPS errors, enabling highly precise autonomous flight, landing, and mission execution for professional applications like mapping and surveying.

For standard high-accuracy RTK positioning, you need two modules: one configured as a stationary base station and one as the rover on the UAV. If you only require dual GPS heading (for compass-free yaw), you also need two rover modules on the aircraft. A single module can function as a standard, non-RTK GPS, but you will not achieve RTK-level accuracy.

The module is directly compatible with open-source autopilots like PX4 and ArduPilot. It includes dedicated cables for connecting to CUAV V5+/X7 series flight controllers and Pixhawk-style connectors. Configuration is performed via its Type-C USB port or UART serial interface using standard protocols like UBX and RTCM.

The rover unit uses a 2dBi gain multi-frequency spiral antenna, optimized for omnidirectional reception on a moving platform. The base station uses a 5dBi gain mushroom head antenna, designed for a stronger, more focused upward signal reception to provide a stable correction source. They are not interchangeable for optimal performance.

The module operates on a voltage range of 4.5V to 6V DC. It is typically powered from a flight controller's GPS port or a regulated 5V BEC. Ensuring a clean power supply within this range is crucial for stable receiver operation and accurate positioning data.
