The 3DM-GX4-15 inertial measurement unit (IMU) and 3DM-GX4-25 attitude heading reference system (AHRS) feature triaxial accelerometers and gyroscopes, and an onboard adaptive Kalman filter. The GX4-25 includes triaxial magnetometers and a pressure altimeter.
The 3DM-GX4-45 Inertial Navigation System (INS) has an onboard pressure altimeter, triaxial accelerometers, gyros, magnetometers, an extended Kalman filter, and GPS.
The sensors feature dual processors, 10°/hr gyro-bias stability, and is fully calibrated and temperature compensated.
