Abstract
A technique for determining a gyro zero voltage is provided. A gyroscope ('gyro') is installed in an automobile as a component of an on-board navigation system. The gyro outputs a voltage representing an angular velocity of the vehicle. The gyro output voltage representing zero angular velocity ('gyro zero voltage') is determined by first determining when the vehicle is stationary based upon the amount of noise in the output voltage of the gyro. When the vehicle is determined to be stationary, the gyro zero voltage is measured.
