Honeywell MEMS rotational rate sensor targets automotive stability control

Honeywell has released a MEMS rotational rate sensor, GG1178, an angular rate-sensing device said to enable low-cost inertial measurement units (IMU) for advanced GPS-assisted navigation systems. The sensors are designed to reduce errors from acceleration and off-axis rotations. Applications include automotive stability control and GPS-aided navigation.

The GG1178 combines a MEMS sensing element and a CMOS ASIC in a ceramic package. The sensing element uses differential capacitance and device symmetry to reduce errors from acceleration and off-axis rotations. The ASIC detects and transforms changes in differential capacitance into an analog or digital output proportional to angular rate.

Sensitivity and output bandwidth are factory programmable.
