MEMS Rotational Rate Sensor

The GG1178 angular rate sensor from Honeywell SSEC, Minneapolis, MN, combines a MEMS sensing element and a CMOS ASIC in a ceramic package and is designed for low-cost inertial measurement units for advanced GPS-assisted navigation systems. The sensing element uses differential capacitance and device symmetry to reduce errors from acceleration and off-axis rotations. The ASIC detects and transmits changes in differential capacitance into an analog or digital output proportional to angular rate. Sensitivity and output bandwidth are factory programmable.
