Research on Analysis and Modeling Method for Repeatability Mechanism of Inertial Navigation System Parameters

针对惯导系统参数长期重复性提出了基于微观过程分析的机理研究和建模方法,可用于揭示惯导系统参数在多环境载荷作用下随时间推移发生变化的机理并建立相应的模型,能够有效指导惯导系统参数变化控制技术方法研究和性能参数变化加速试验方法研究,从而为解决惯导系统参数长期重复性问题奠定机理和模型基础。

The Long-term repeatability of parameters of INS （inertial navigation system） is one of the most important tech- nical matters which has effect on fighting efficiency and maintainability of modem precision-guided weapon. A research and modeling method based on microscopic analysis is proposed for revealing the mechanism and building models of changes on INS parameters initiated by multi-environmental loads and time. Controlling means and accelerated test methods for the changes of INS parameters can be researched on this basis, which is the foundation for solving the problems caused by longterm repeatability of INS parameters.
