C-RTK 2 PPK Module

First PPK module in the open source community

C-RTK 2 Overview

C- RTK 2 is a high-performance PPK/RTK positioning module created by CUAV for professional application fields such as UAV aerial survey; It integrates light appearance, industrial grade IMU, multi-star and multi-frequency satellite receiver, supports both RTK centimeter-level positioning navigation and RAW data recording for post-differential calculation. Supports shutter triggering and hotshoe synchronization. It adopts CAN bus protocol and is compatible with PX4/ArduPilot open-source flight controller. It can be applied to various specifications of multi-rotor, VTOL fixed wing, helicopter and other industrial use UAVs.

Both RTK&PPK are Supported

C- RTK 2 supports both RTK and PPK functions and supports up to 25Hz raw data recording. It is very suitable for surveying and mapping, unmanned driving, unmanned vehicles, inspection, agriculture and other fields.

Less Control Point

By using C-RTK 2 for mapping, the control point can be reduced by more than 80%. With the use of professional mapping camera, can even realized control point free

High Performance H7 Processor

C- RTK 2 uses STM32H7 processor, STM32H743 processor, Cortex-M7 core (with double-precision floating point unit), running frequency as high as 480MHz,2MB Flash,1MB RAM, running real-time system, enable C- RTK 2 to work efficiently and stably

Support Shutter and Hotshoe Trigger

C- RTK 2 supports double triggering of shutter and hot boot at the same time, and obtains more accurate Pos data through real-time communication between hotshoe and camera.

Built-in High-Precision Industrial IMU

C- RTK 2 built-in high-precision industrial grade ICM-20689 accelerator & gyroscope, RM3100 electronic compass, ICP10111 barometer, can be configured for flight controller external IMU, and can be shot in the posture, rich information such as elevation is recorded in POS data.

High-Speed USB Reading

C- RTK 2 supports reading data on the memory card directly through the Type-C data cable connected to the computer, with a speed of up to 48 M/s. It supports up to 32G TF card, it can quick config by text file

Dual Platforms Support Plug&Play

C- RTK 2 adopts UAVCAN/Dronecan bus protocol; Perfect compatibility with PX4/ArduPilot; With CUAV series flight controllers, plug and play can be realized
