CUAV C-RTK 2 RTK PPK GNSS Module

The CUAV C-RTK 2 is a dual-mode GNSS positioning module built around the u-blox F9P multi-band receiver, delivering centimetre-level accuracy for agricultural drones, survey platforms and autonomous long-range builds. It runs both real-time kinematic (RTK) corrections and post-processed kinematic (PPK) logging, and pairs natively with ArduPilot and PX4 flight controllers for precision waypoint navigation, field mapping and georeferenced data capture.

Key features

• u-blox F9P receiver tracks GPS, GLONASS, Galileo and BeiDou simultaneously for centimetre-level RTK positioning (0.01 m + 1 ppm CEP)
• Dual-mode operation: live RTK corrections for real-time missions, or 25 Hz raw-data logging for PPK post-flight processing
• Built-in ICM-20689 accelerometer/gyroscope, RM3100 electronic compass and ICP-10111 barometer feed attitude and altitude data alongside positioning
• Hot-shoe trigger input timestamps camera shutter events for direct georeferencing of aerial photos in mapping workflows
• STM32H743 H7 processor (480 MHz, 2 MB flash, 1 MB RAM) runs the onboard real-time system for stable, efficient operation

Specifications

• Protocol: UAVCAN/DroneCAN
• USB: high-speed USB-C with U-disk mode for raw-data download
• Compatibility: ArduPilot and PX4; plug-and-play with CUAV X7-series flight controllers
• In the box: C-RTK 2 module, multi-band helix antenna with 50 cm feeder, 35 cm CAN cable, 35 cm shutter cable, 30 cm hot-shoe cable, 30 cm trigger cable, 20 cm 3-pin Dupont lead, 40 cm Canon 2.5 mm and 30 cm Sony USB shutter-trigger cables, hot-shoe PCB, USB-C cable

Using C-RTK 2 for mapping can cut ground control points by more than 80%; paired with a professional mapping camera and the hot-shoe trigger, control-point-free surveys become possible. Pair with a compatible flight controller and either an RTK base station for live corrections or log raw data for PPK post-processing.
