摘要
挠曲变形是主/子惯导在线标定的一种重要误差源,对其补偿处理具有重要意义。首先,分析了挠曲变形的概念、特点及其对主/子惯导误差方程影响;其次,将现有补偿处理方法分为3大类,分别为测量方法、机理建模方法和随机过程建模方法,并讨论了他们各自的优缺点;最后,探讨了挠曲变形补偿方法的发展方向。
Flexure deformation is an important error sources of master / slave INS online calibration. It is great significance to compensation those errors. In the analysis of the flexure of the concept, characteristics and post-master INS equations influence the process, the existing compensation processing methods were divided into three categories, namely, measure- ment method, mechanism modeling and stochastic processes modeling. Then the advantages and disadvantages were dis- cussed. Finally, the development direction of the flexure deformation compensation method was discussed.
