动基座对准条件下惯性制导精度评估方法
Evaluation Method for Inertial Guidance Accuracy Under Moving Base Alignment
摘要
Abstract
To solve the issue of evaluating inertial guidance accuracy under moving base alignment conditions,a method for evaluating the accuracy of inertial guidance is studied,considering both tool error and initial error.Firstly,the influence of initial er-ror and tool error on the accuracy of inertial navigation calculation is derived and analyzed.Then,based on the relationship between the navigation parameter error of the active segment endpoint and the deviation of the guidance landing point,a guidance accuracy evaluation method is proposed.Finally,Monte-Carlo simulation is used to evaluate the inertial guidance accuracy corresponding to each individual error and comprehensive error.The research results indicate that,except for the primary tool error and initial posi-tion error related to the Z-term visual acceleration,which have a relatively small impact on guidance accuracy,other initial errors and tool errors have varying degrees of impact on guidance accuracy.Effective measures can be taken to correct and compensate for initial errors and tool errors to improve guidance accuracy.关键词
