Abstract
The invention relates to a novel method for gyroscope orientation measurement. The method uses a gyroscope total station consisting of a total station and a gyroscope for measurement. The method comprises the following steps that: firstly, on a known measuring line outside a hole, the levelness of the total station is calibrated according to coordinate azimuth and gyroscope orientation measurement values; secondly, gyroscope orientation measurement is carried out on an undetermined measuring line inside the hole, and the read numbers of the gyroscope and the total station are added up; finally, the calculation result is added into the difference of meridian convergence angles between measurement sites inside and outside the hole, and then the coordinate azimuth of the measuring line inside the hole can be obtained. Compared with the prior gyroscope orientation method, the method can finish the measurement of the coordinate azimuth of a traverse side inside the hole without calculating meridian convergence angles and instrument constants.
