Abstract:
The patent relates to a self-alignment system for a gyro-stabilized platform. The system uses the earths rotation rate, sensed by an east-west oriented rate gyro mounted on the platform, to drive the approximately aligned platform into E-W and N-S alignment with a high degree of accuracy. The accuracy is gained by employing a comparison technique to separate the gyro output signal of earths rate from the random part of the output caused by imperfection in the gyro.
