Whole-automation north-finding technology of gyro-theodolite

The working theory of gyro-theodolite is analyzed to explore and implement the key technology of its digitization and full automation, which makes a foundation for the fully automatic gyroscopes. Gyroscope digital measuring unit, sensitive component automatic rising and lowing unit and automatic coarse north-finding control unit, controlled by DSP and CPLD and combined with full automation north-finding scheme, make up of a whole-automation intelligent north-finding experimental system. The system could collect the moving curve of the cursor automatically, operate automatically and intelligently, and compute and display the north-finding results,and so on. The north-finding precision is 6.3" when the north-finding time is 12 min and the north-fmding preci-sion is 18.7" when the north-finding time is 4 min.
