摘　　要：设计机载捷联惯导传递对准效果及性能的仿真平台。通过研究传递对准惯导理论,分析各组成模块,提出用Visual c++与Matlab混合编程技术实现平台的搭建和仿真解算。种设计方案避免了用VC++建立传递对准数学模型,简化了编程的难度,同时避免了Matlab运行速度慢的缺点。仿真结果证明平台可以分析机载捷联惯导传递对准效果及性能,并能够设置惯导系统的各项仿真参数,适应不同精度的惯导系统的仿真要求,并能够规划多种航迹,用于传递对准方案的精度评估,为实际飞行中的动基座快速对准提供参考,并大大降低了传递对准仿真的工作量。The article studies and compiles the effects and performances of transfer alignment algorithm for Airborne strapdown intertial navigation system. After the transfer alignment algorithm is studied and the modules of the visualization simulation platform are analysed, the platform construction and simulation calculation are realized by a mixed programming of Visual C ＋ ＋ and Matlab. This method avoids building maths module for transfer alignment by VC ＋ ＋ , simplifyies the programming difficulties and avoids low speed of Matlab. The simulation results show that the simulation platform could analyse the effects and performances of transfer alignment algorithm for the Airborne strapdown intertial navigation system , and can set up various parameters of inertial navigation systems to fit the emulation requirement of inertial navigation systems ,which are different in precision. The platform can also mark out various flight path models and evaluate the precision of alignment to supply reference for fast transfer alignment on moving base in practical flight , and to reducee the workload of transfer alignment emulation.
