捷联惯导系统软件测试中的仿真飞行轨迹设计及应用

Design and Application of Emulation Flight Trace in the Software Test of Strapdown Inertial Navigation System

介绍了一种针对捷联惯性导航系统进行软件测试的仿真飞行轨迹的设计方法。该方法根据实际情况 ,将各种典型的机动动作做成了单个的模块 ;然后再根据需要测试的性能将各个机动动作自由组合成一条飞行轨迹进行实时仿真测试。笔者利用该飞行轨迹设计方法设计出一些典型的飞行轨迹并应用于我国某型捷联惯性导航系统的软件测试中 ,为系统性能、精度的提高作出了重大贡献。

A design method of emulation flight trace is introduced aiming to detect the software of strapdown inertial navigation system.According to the practical condition,this method made the various typical flight movements to single parts.The single parts can be combined randomly to a flight trace on the demand of detect,and then the flight trace can be used for real time emulation detect.This design method of flight trace is now applied in the software detect for a kind of strapdown inertial navigation system of our country,it will contribute greatly to the improvement of system performance and precision.
