Cadastral New Method for Measuring Based on the Level Sensor_ FOG_TS Combination

HAO Chunling;Bohai Shipbuilding Vocational College;  
In order to solve the problems of measurement techniques which has inefficient,time-consuming and observing environmental impact seriously defective. The technology of FOG north finding was combined with inclination measurement which will be used in cadastration. It gives steps of misalignment self-compensating of FOG; And it reduce errors in fiber optic gyroscopes( FOG) to improve its performance. FOG accuracy 0.05 ° / h in case,when the angle measurement error of 1',the directional error is 26. 51″. The results show the practice has proved that the FOG measurement's precision can meet the request.
