CUAV C-RTK 2HP Positioning Module (Dual antenna RTK)
Description
CUAV C-RTK 2HP Overview
CUAV C-RTK 2HP is a dual antenna RTK and GNSS module that can achieve centimeter-level positioning accuracy. Using two C-RTK modules, one installed on the base and the other installed on the UAV, a real-time GNSS system is designed. By using dual GPS on the plane, you can replace the compass and have a dual GPS yaw.
This is desirable due to the error of the compass coming from electromagnetic interferences, suitable for environments with high noise. Compatible with open-source autopilots like PX4 or Ardupilot, this RTK gps module is an ideal choice for aerial performance and agricultural applications. You can have high-precision take-off, landing, and missions.
Dual Antenna Integration for Centimeter-Level Precision in Seconds
The beautiful thing about 2HP is that instead of using two RTK modules, you can connect two RTK antennas to the C-RTK 2HP, and it does the job of two RTK modules for you and can find the UAV direction. For example, C-RTK 2HP can do the job of two C-RTK 9Ps rover modules.
Due to using multiple satellites and multiple frequencies, and with the help of advanced RTK algorithms, the position of the base station converges and provides centimeter-level differential data in less than 10 seconds.
