Theodolite self-stabilization tracking servo system based on mobile platform

In order to improve the tracking and positioning accuracy of theodolite self-stabilization tracking based on mobile platform, the position of object is transformed from platform coordinate system to earth coordinate system by using coordinate axis circumrotation. A method of forecast tracking technique based on mobile platform is presented. The former compound angle is transform from platform coordinate to earth coordinate. The next compound angle is forecasted in earth coordinate, finally the forecast result is transform to the platform coordinate. The stable tracking technique based on mobile platform is realized. This forecast result is compared with direct forecast in platform coordinate. Tracking and positioning accuracy can be enhanced from 5´ to 1.5´, which fully prove that this forecast technique is more accurate and propitious to realize stable tracking on mobile platform.
