Witmotion WTGAHRS IMU with Built in GPS Attitude Angles and Position Sensor (Static 0.05°, Dynamic 0.1°)
LE 8,000.00
WTGAHRS from Witmotion is IMU system with built in GPS. The IMU contain 3 Axis gyro, 3axis accelerometer and 3 axis magnetic compass, magnetometer. The GPS is integrated with IMU using kalman filter. It is INS-GPS navigation system, enables to measure attitude angles in Pitch, Roll and Yaw directions (Angles rotation around X, Y, Z axis) and also LAT, LONG and ground speed measurements.
Features
- Output TTL .
- Input Voltage: 5 - 36V.
- The attitude measurement accuracy up to Static 0.05°, Dynamic 0.1°.
- INS with built-in GPS
- aluminum casing for magnetic interference and shock resistance
- External GPS antenna.
