Tuning fork MEMS gyroscope for precision northfinding

We report northfinding results using an out-of-plane tuning-fork MEMS gyroscope with performance approaching navigation grade. Angle random walk is less than 0.003 °/√hr, and in-run bias instability is less than 0.02 °/hr at an Allan variance sampling time of one hour. A compact (
