A Method of Reducing Random Drift in the Combined Signal of an Array of Inertial Sensors

Abstract

The present invention relates to the components of inertial measurement units, sensors such as gyroscopes and accelerometers. More particularly, the invention relates to a method to calculate optimal weights for use in combining the signals from an array of gyroscopes or accelerometers into a single, low-drift signal to improve the resonant sensor bias stability relative to a single gyroscope or accelerometer.
