平台惯导系统飞行试验性能误差分析

针对某型平台式惯导系统试飞中存在的性能超差现象,对惯导系统误差机理和飞行数据进行了分析,提出了影响飞行性能的误差因素。根据分析结果,从提高惯性元件精度和对相关误差进行标定和补偿两方面采取措施对惯导系统进行改进。改进后的惯导系统经过试飞验证,其性能满足设计指标,表明所采取的改进措施有效可行。

Flight test performance error analysis of the platform inertial navigation system

To the phenomenon that the flight test performance of certain type inertial navigation system could not meet the design demand,the paper analyzes the system error mechanism and the flight test data,and presents the error factors that affect the system flight performance.According to the analysis result,some measures have been taken to the system from improving the precision of the inertial sensors and aligning and compensating the system errors.The flight test result shows that the system performance meet t...
