摘要: 针对惯性导航系统随时间误差积累的特性,设计了一种基于VC++的SINS/GNSS组合导航的仿真系统。根据飞控模块模拟飞机实际飞行轨迹,从而产生惯性测量器件的真值数据。利用Visual Studio2005完成捷联惯导实时解算和全球导航定位系统仿真,完成输出校正,从而实现组合导航系统的动态数字化仿真。程序结果表明组合导航系统可以克服惯性导航系统随时间误差积累的特性,导航参数误差不随时间漂移,可以用于长时间导航。

Abstract: For errors accumulating over time, a simulation system of SINS/GNSS integrated navigation based VC++ is design. According to  the actual flight path of simulate aircraft flight control module, the true value of inertial measurement device is obtained. Using Visual Studio 2005, the realsolvers and GNSS simulation are finished, and the output correction is completed, enabling dynamic digital simulation of integrated navigation system. Program results show that the integrated navigation system can overcome the error accumulation feature of the inertial navigation system, navigation parameter error does not drift over time, can be used for a long time navigation.
