In order to meet the high-precision measurement requirements of the ultra-long position parameters of rocket skids, a collaborative network measurement method using a laser tracker and a total station was designed, which can integrate the advantages of the both systems. The coordinate control field is introduced to construct the constraint field and the constraint equation. The weights are used to optimize the weights, and the Levenberg-Marquard optimization algorithm is used to solve the optimal solution of the equations. Tests were performed under field conditions and the accuracy was analyzed and compared with the standard length of the reference ruler. The results show that the measurement error is kept at 3 mm within the range of 3 km, which realizes high-precision and high-efficiency measurement of ultra long distance position information.
