The Battle Between MEMS and FOGs for Precision Guidance

Fiber optic gyroscopes (FOGs), previously the low-cost equivalent to other technologies such as ring laser gyroscopes (RLG), have some fresh competition. Microelectromechanical system (MEMS) gyroscopes are beginning to take market share away from traditional FOG applications. Specifically, antenna array stabilization, agricultural machine control, and general vehicle navigation are the battlegrounds where MEMS and FOGs faceoff.
