【摘要】 在对惯导系统精度评估标准统一化研究中,在一定的假设条件下,推导、归纳、整理了四类定位精度的评估算法(TRMS、RMS、σ和CEP)及相应的7个指标间的工程换算关系;利用某型捷联旋转惯导4次实际导航数据进行了仿真分析,从推断算法、指标间换算关系、精度折合效果等方面进行了对比验证,基于理论分析和仿真验证结果表明TRMS评估算法及试验简单且易于转换,并对其精度折合给出合理化建议。更多还原

【Abstract】 Four types of assessment algorithms and the seven project conversion relationships were derived and inducted under certain assumptions,in the integrated research of Inertial Navigation Systems(INS) evaluation methods;A simulation analysis was studied by use of the 4 tests data from one type of strap-down INS(SINS),from the inference algorithm,index conversion relations and precision equivalent results to contrast verification.The results showed that the evaluation algorithm and experiment of Time Root Mean Square error(TRMS) are simple and easy to convert,and how to use the reduced factor was suggested by theoretical analysis and simulation.更多还原
