This paper presented a new kind of measurement mechanism for the position and attitude measurement of a moving object in plane. The mechanism and the measurement principles were described and the error models were built by using differential law principles. Analysis of practical applications and the simulation demonstrate the feasibility of the method. This mechanism with characteristics of high precision and simple structure and is suitable to complete high--precision and large-- space plane movement measurement under some special measurement conditions.
