Traditional lift type mechanical gyroscope is adopted as the experimental pattern to seek the key technique of intelligence and complete automation.Digital measuring subsystem of the gyroscope

automatic coarse north-finding subsystem based on electronic compass

automatic rising and falling subsystem of the sensitive component and intelligent control subsystem based on MSP430 and CPLD are established and all subsystems are controlled by an integrative software control system.The automatic north-finding system is implemented.A lot of north-finding experiments carried out in the lab shows that the measurement system is stable and effective

and the north-finding precision is within 8″.The automatic north-finding system of gyroscope is easy to operate

and improves the north-finding efficiency and precision

which lay the foundation for gyroscope to achieve complete automation and intelligence.
