Targeting aerospace and industrial markets, the 3DM-GX4 family of miniature 10°/hour inertial sensors employ MEMS sensor technology. The 3DM-GX4-15 Inertial Measurement Unit (IMU) and 3DM-GX4-25 Attitude Heading Reference System (AHRS) feature tri-axial accelerometers and gyroscopes plus an onboard Adaptive Kalman Filter. In addition, the GX4-25 also includes tri-axial magnetometers and a pressure altimeter. The 3DM-GX4-45 Inertial Navigation System (INS) features an onboard pressure altimeter and tri-axial accelerometers, gyros, and magnetometers. It also includes an Extended Kalman Filter and GPS to generate optimal inertial and attitude estimates. The GX4-15 and -25 weigh 16.5g and the GX4-45 weighs 20g. Each sensor features dual processors, 10°/hour gyro bias stability, and is fully calibrated and temperature-compensated.
