  3. In this dissertation, we studied the tcra1101plus total station position system, which introduced the principle and characters of the instrument ' s closed loop tracking system. also we explained the cause of prism ' s position error and brought forward mathematic model to correct, moreover, the good results has been drawn form the expenriments. the kinetic survey system have been realized, which the sampling rate attain more than 5hz and the position precision can be less than 2mm on condition that targeted - point moving slowly at the velocity below 2cm / s. having finished the survey system to examine whether the fine - tuning stewart platform in good status, we have finished mensurating the position reference of the fine - tuning stewart platform and the offset of the prism
