Directional accuracy is one of the most important factors that it will impact the application of the maglev gyro total station.At present,it is used for calculating the apparatus directional angle data which is to use the triple variance (?σ ) method to eliminate the error influence.According to the instrument collecting mass of non-stationary stochastic time series data characteristics and the traditional theory of mathematical statistics of error eliminatingmethod,it is obviously not suitable.This paper is analyzed and modeled by the method of time series analysis,and analysis of equipment acquisition the rotor current error sequence properties through calculation of programming toestablish the error model to self correction rotor current data.It can effectively improve the instrument orientation results and improve the precision of directional angle.Combining with practical sampling data,a error series analyzing and modeling method of the maglev gyro total station is presented.Simulation results show that the proposed approach is satisfactory.
