A North Finder , also called a north seeker or gyrocompass module , is a high-precision inertial orientation device that determines True North using Earth’s rotation instead of a magnetic compass. It typically integrates a fiber optic gyroscope (FOG) or MEMS gyroscope , accelerometers, a rotation/indexing mechanism, and a DSP/MCU for azimuth calculation. Unlike a magnetic compass, a north finder is immune to steel, magnets, power lines, and electromagnetic noise . It
