CUAV C-RTK 9Ps RTK GNSS Module for Pixhawk

The CUAV C-RTK 9Ps is a high-precision RTK GNSS positioning module engineered for Pixhawk-based autopilot systems, delivering centimeter-level accuracy for professional UAV applications. Designed for agriculture drones, surveying rigs, mapping platforms, and autonomous long-range builds where standard GPS (metre-level accuracy) falls short, this module integrates seamlessly with ArduPilot and PX4 firmware.

Key features

• RTK (Real-Time Kinematic) positioning for centimeter-level accuracy, enabling precision tasks such as crop spraying, terrain mapping, and waypoint missions

• Multi-constellation GNSS support (GPS, GLONASS, Galileo, BeiDou) for robust satellite coverage and faster fix acquisition

• Direct compatibility with Pixhawk flight controllers and CUAV autopilot ecosystem via standard UART interface

• Requires RTK base station or NTRIP correction service for differential positioning; ideal for fixed-wing, heavy-lift, and agriculture platforms

• Two modules on the aircraft can compute GPS yaw and replace the magnetic compass, useful near power lines and other magnetic interference

Specifications

• Receiver: u-blox ZED-F9P, 184-channel, multi-band

• Constellations: GPS, GLONASS, Galileo, BeiDou (4 concurrent)

• Compass: IST8310

• Positioning accuracy: 0.01 m + 1 ppm CEP (RTK)

• RTK update rate: 20 Hz

• Convergence time: under 30 s

• Antenna gain: 2 dBi (rover), 5 dBi (base)

• Interface: USB Type-C on the module, with UART cables for Pixhawk-series controllers

• Weight: 30 g (module)

• Operating temperature: -40 to +85 C

• Firmware: PX4 and ArduPilot

Choose the full kit (Base + Rover), the base or the rover on its own, or the rover air unit without its stand. Mount this module on your autopilot build when your mission demands repeatable positioning accuracy — automated field operations, photogrammetry, and long-range autonomous navigation all benefit from RTK's sub-decimetre precision over standard GNSS.
