GRTK For Ardupilot
- High precision RTK module, supporting yaw by 2 antennas, very easy but efficient for positioning and orienting.
Introduction
-
GRTK is a dual-antenna high-precision differential positioning and directional module (Real Time Kinematics) independently developed by Blicube. A complete RTK system can be formed through two GRTK modules (one mobile terminal and one base station terminal).
-
The module is based on a new generation of high-performance GNSS SoC chip ,supports multi-system multi-frequency RTK positioning, supports dual-antenna high-precision orientation, and supports GPS & GLONASS & Beidou & Galileo & QZSS navigation and positioning. Widely compatible with high-precision positioning and orientation requirements such as drones, robots and intelligent driving.
