Abstract
The disfigurement of gyroscope made in our country is described.The optics system construction and working principle of north-finding gyroscope system base on CCD and microprocessor technology are described.The formula of complex method of gyroscope direction and the math models of the complex method in the environment of microprocessor are given.It is proved to be effective through experimentation.The conclusions show that the system can shorten the measuring time
simplify the operation
and improve the north-finding accuracy of gyroscope.The criterion error can be controlled in the circle of 10″.
