Witmotion WTGAHRS3 IMU with Built in GPS Attitude Angles and Position Sensor (Static 0.05°, Dynamic 0.1°)

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.
