[0024] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0025] Take the main process of calculating the true north position of the target point of the launch vehicle as an example below to illustrate the specific implementation process of the present invention, as figure 1 As shown, firstly, the spatial orientation point P is precisely measured by the gyro theodolite 1 ,P 3 The true north orientation of the line α i ; Then the laser tracker precisely leveled and measured the orientation point P 1 ,P 2 and P 3 The coordinate value in the instrument coordinate system (X i ,Y i ,Z i ), and calculate the orientation point P 1 ,P 2 The azimuth angle value β in the laser tracker coordinate system connected with the measuring point; according to the different azimuth values (α, β) corresponding to the orientation point, the conversion parameters between the gyro theodolite coordinate system a...
