Abstract :
A Quartz Rate Sensor (QRS) family based on the Coriolis effect is presented. The architecture is highly capable of detecting internal failures. The MEMS solid-state rate gyro (known by the trade name GyroChip(R)) consists of a third generation microminiature double-ended quartz tuning fork, as well as third generation electronics in the form of a mixed signal ASIC. The high reliability device has no wearout mechanisms and features a micromachined sensing element. The sensor requirements, theory of operation, architecture, packaging family and performance parameters are described. In addition, system safety considerations and a description of the comprehensive self-monitoring features are provided
