基于POS虚拟测试模型的惯性器件误差辨识研究

he inertial instrument error as the main sources of position and orientation system(POS) affects the accuracy. In order to identify the error model of inertial navigation system(INS) from test data, a new identification method was proposed. Through the reverse process of strap-down inertial navigation, the ideal inertial instrument output data could be solved from navigation result. The error compensation system can be established, with ideal data input and the actual data of the inertial instrument output. The test results show that the method is effective and has some reference values and some directing significance for engineering application.
