Paper Abstract

In order to solve the problems and shortcomings of current angle measurement methods for satellites assembly and inspection, such as limited field of vision, relatively low precision and low degree of automation, a novel design of high accuracy angle measurement system is proposed. The new system composed of auto-collimator, electronic gradienter, two-dimensional precise turntable and standard mirrors works by actual collimation measuring among the measured target, auto-collimator and standard mirrors with the measuring basis of earth which is built by electronic gradienter. This paper focuses on the specific structure design, engineering modal and arrangement plan of automatic measuring, also includes precision calibration test in the end. According to the result of the test, the angle measurement system reaches the precision of 3″and repeatability of 1.1″.
