A digital angle detecting system is studied for the electrostatic sustained gyroscope,as a high accurate inertial device,which has a high requirement of the resolution and the stability to the polar axis position.The system,based on the sawtooth pattern on the equatorial plane of the ball rotor,uses optical sensor to pick up signal,and converts the position signal of equatorial plane of the rotor into a pulse signal through a special circuit the design of the angle detecting system and its error is discusse...
