The main factors that affect the accuracy of guidance tool error linear model estimation are the remote measurement accuracy and the pathological problems of environmental function matrix. In this paper, the influence formula of telemetry accuracy on telemetering is deduced in detail, and the morbidity problem of mitigating the matrix of environmental function is analyzed by using the optimal model and parameter estimation method. Simulation results show that the higher accuracy of the observed data, the appropriate optimization model and the parameter estimation method are the key factors to improve the accuracy of the guidance linear error model.
