The Orientation Method And Data Processing Research On Total Station Gyroscope

Total station gyroscope can determine the true north direction quickly and precisely at any time and anywhere, and obtain the coordinate azimuth without considering the intervisibility condition or any auxiliary, even do not need to use the given points. It can be widely applied in substructure work.During the orientation process of high-end gyro theodolite, it requires the worker to lower the instrument artificially and track the instrument continuously. It needs an intense working strength, and the succeeding data processing is also very complicated. Whereas the characteristics mentioned, the paper puts forward a way to simplify the coarse orientation procedure of the high-end auto gyro theodolite:analyse the null position correction, research the application scope and the stability of the instrument, and write a data processing program about the reversal point method to improve the efficiency of high-end auto gyro theodolite.By experiments and the data measured at Shenyang subway station this paper mainly researched the following content:1?Study the essence of the coarse orientation in the process of the gyro orientation, and designed a simplified scheme about the coarse orientation procedure.2?Study the ellipsis of null position in special conditions.3?Study the stability of high-end auto gyro theodolite and the application scope of the instrument constant.4, Contrast the advantages and disadvantages of the reversal points method and transit method of high-end auto gyro theodolite.5?Write the reversal point orientation method data processing program,make the rapid output of the work achievements come true.
