摘要
随着时间的推移,部分惯导平台参数的稳定性会发生比较明显的变化。为分析其变化情况,提出了惯导平台测试数据的小样本等时间间隔二次修正插值法,以此来构建惯导平台测试数据的时间序列。通过对已有的小样本测量数据进行准确插值,获得样本容量较大的等时间间隔的时间序列,在此基础上,通过时间序列建模的方法来研究惯导平台误差系数的变化情况,为惯导平台的使用提供指导。
The values of some parameters of the inertial navigation platform are time-varying.To analyze the changes,this paper presents the small sample interpolation interval two revisions of test data of inertial navigation platform,in order to build the test data time series of inertial navigation platform.On small samples have been accurately measured data interpolation,to obtain a larger sample size,such as interval time series,on this basis,through the time series modeling approach to study the inertial platform error coefficient of variation,to provide guidance on the use of inertial navigation platform.
