The methods for reduction results are discussed in our paper Especially, the improvment for the error of the azimuth depended on the working catalogue and the transit instrument has been discussed.
After that, rotating the sensitive axis of the gyro to point the true north, the instrument is working in the azimuth mode to constantly display azimuth angle of the carrier.
