C-RTK module GPS for Pixhawk Flight Controller

C-RTK GPS Flight Controller GPS with Protective Shell for PIX PX4 Pixhawk pixhack

High-precision positioning: Many drone applications require higher accuracy than traditional GNSS offerings, such as drone mapping, agricultural surveying, and high accuracy takeoff and landing.

C-RTK is a Real Time Kinematics module for mass market launched by CUAV. The complete RTK system can be composed of two C-RTK modules (one for aircraft and one for base station)

Small body, big power

Integrating the RTK GPS (M8P) + GNSS system dual positioning module and a COMPASS geomagnetic compass in just 53MMX32MM volume greatly reduces the need for aircraft installation volume, increases reliability and greatly reduces hardware costs.

CNC aviation aluminum alloy shell

C-RTK uses a CNC formed aluminum alloy shell, in addition to reducing external electromagnetic interference, reliability and durability also have some improvement

Double-ended design

The use of TYPE-C interface design, clever use of port redundancy design, the aircraft end and ground end only need to insert different specific data line can be double-ended switching, convenient and rapid iteration, reduce operating costs

Centimeter level positioning

Run advanced differential algorithm, so that the positioning accuracy of centimeter level positioning accuracy.

Centimeter-level high-precision positioning

Advanced differential algorithms are used to achieve positioning accuracy of centimeter positioning accuracy.

Many drone applications require higher accuracy than traditional GNSS offerings, such as drone mapping, agricultural surveying, and high-precision takeoff and landing scenarios. The C-RTK differential module quickly cuts through to the vast majority of applications requiring precise positioning .
