RGA300CA is a Micro-Inertial System comprised of a MEMS gyro and triaxial accelerometer subsystem. It is the ideal solution for land vehicles where the majority of the motion control occurs on the yaw rate axis. The unit is compensated for static errors using an on-board DSP processor. Outputs are available in both analog and digital (RS-232) formats. Data is available in a polled mode or continuously at a fixed rate of over 100Hz. No recalibration of the unit is required, and it is designed for a long service-free operating life. The MEMS angular rate sensor is equiped with a Z-sensitive axis, also known as yaw rate. In addition to the rate sensor, a triaxial silicon MEMS accelerometer is included in the RGA300CA system. The triaxial accelerometer is a bulk-micromachined capacitive accelerometer. The accelerometer outputs can be used in one of two ways. In GPS augmentation applications, the accelerometers can be used to estimate X, and Y velocity by performing a single integration of the outputs. A second use for the acceleration signals is an inclinometer. The acceleration sensors have DC response, which can be used to measure roll and pitch in static conditions.
