WIT Motion WTRTK-4GB IMU GPS-RTK Wireless Bass Station Module High Precision Differential Positioning UAV GPS Module

Difference:
- WTRTK-4GB: RTK wireless base station module; 4G communication; 50km wireless connection distance; Function: Provide differential data information.
- WTRTK-4GR: RTK wireless positioning module; 4G communication; 50km communication distance for self-developed base station, national coverage for Qianxun SI (developed on the basis of Beidou); Function: Mobile station receives differential data and outputs centimeter level positioning data.
- WTRTK-4DR: RTK wireless positioning and orientation module; 4G communication; 50km communication distance for self-developed base station, national coverage for Qianxun SI (developed on the basis of Beidou); Function: Mobile station receives differential data and outputs centimeter positioning data direction information, with inertial navigation function.
- WTRTK-LoraA: RTK wireless positioning and orientation module; Lora communication; 2km communication distance; Function: Mobile station receives differential data and outputs centimeter level positioning data.

Description:
- Multi-band receiver provides centimeter-level positioning accuracy in seconds. Simultaneous reception of GPS, GLONASS, Galileo and Beidou.
- Advanced anti-interference technology and calibration technology ensure the security of location and navigation information.
- High precision inertial navigation, WTRTK-4GA heading angle fusion IMU data, can still output accurate heading angle without GPS signal. WTRTK-4GA integrates IMU data and utilizes pure inertial navigation to achieve high-precision positioning.
