The space target captured remote sensor is more and more applied in the field of deep space exploration. It can capture the space target quickly and accurately with high-precision multi-dimensional adjustment mechanism. The attitude adjustment of the remote sensor is based on the coordinate system of the adjusting mechanism. At the same time,in order to eliminate the influence of the asymmetric field angle of the remote sensor caused by the inconsistency between the optical datum of the remote sensor and the coordinate system of the adjusting mechanism, the angle matrix between the optical datum and the coordinate system of the adjusting mechanism should be measured when the remote sensor is installed with the adjusting mechanism. Moreover, the space angle between the optical datum of the sensor and the coordinate system of the adjusting mechanism should be adjusted to meet certain tolerance requirements. A method of using laser tracker in the same coordinate system to achieve optical datum and mechanical datum measurement at the same time is introduced, and then the angle matrix between them is established. Then the electronic theodolite monitors the optical datum of the capture remote sensor in real time to realize the accurate installation of the capture remote sensor and the attitude adjustment mechanism, and the installation accuracy can be controlled within 10".
