In this column, guest contributor Mike Horton from ANELLO Photonics introduces a new gyro technology that bridges the market gap between high-performance (but expensive) sensors (fiber-optic and ring laser gyros) and low-cost (but imprecise) MEMS gyros. Benefits of improved gyro quality enabled by SIPHOG are illustrated, including GNSS-denied navigation scenarios.
