Overview
CUAV C-RTK 2 is a GNSS module supporting both RTK and PPK. It can record raw data and shutter recording, and can be used as a mobile station or base station. It uses CAN bus communication mode, supports high-speed USB and TF card storage, and integrates an RM3100 electronic compass, an ICM-20689 accelerometer & gyroscope, and an ICP10111 barometer. The module uses an STM32H7 (STM32H743) processor and is compatible with controllers running ArduPilot/PX4 firmware.
Key Features
- Supports RTK & PPK simultaneously
- Multi-satellite, multi-frequency receiver (u-blox ZED-F9P)
- Up to 25Hz raw data recording (PPK)
- Hotshoe trigger support, plus shutter in/out triggering
- Supports UAVCAN (DroneCAN) protocol via CAN interface
