Automatic Real-Time Magnetometer Error Compensation and Calibration
Agency / Branch:
DOD / ARMY
The proposed effort in this SBIR program is to develop an auto-compensation method for field deployed, strap-down magnetometers. The solution we propose is a system solution that includes sensor design, initial calibration, use of auxiliary field sensors, and automated field compensation methods. The TIAX proposed solution considers aspects of the magnetometer, CPU, IMU, and GPS system within the player unit, to one degree or another. The principal focus of the offering is on the magnetometer and the inertial measurement unit. The output desired from an orientation measurement device is roll and pitch attitude angle with respect to the local horizontal plane, and the heading angle relative to true (geographic) North. Pitch and roll are computed from the IMU signals and are referenced to the local gravity vector. Heading angle to true North is a more complicated matter and is the principal subject of this proposed effort.
