Targeting systems require maximum accuracy at all times and under all conditions. Whether hand-held or mounted on tri-pods, vehicles, or weapons, the system must perform reliably and consistently to meet the needs of today’s warfighter.
Heading and azimuth angle are vital components for accurate targeting. The complex nature of targeting systems presents significant challenges to obtaining maximum accuracy reliably, quickly, and repeatedly. Magnetic disturbances, whether produced by external sources or internal components of the system, cause errors in the output of conventional digital magnetic compasses (DMCs).
A complete system integrating MEMS inertial sensors, magnetometers, and algorithms to process and manage sensor data is required to overcome the difficulties of this complex application. All this must be accomplished in a small, lightweight package with minimum power consumption.
