摘要
通过建立高精度的航天器轨道摄动模型,可以显著地提高GPS导航信号模拟器的仿真精度。文章通过借鉴现有的高精度轨道摄动模型的研究成果,将其产生的轨道数据引入到GPS导航信号模拟器的数学仿真流程之中,并对最终的仿真性能进行比对分析。结果表明:在采用所介绍的应用方法后,能够有效地提高GPS导航信号模拟器的工作性能。此研究结果也可为后续GPS导航信号模拟器产品的研制和开发提供参考。
By building aperturbation model of spacecraft orbit with high precision,we can improve the simulation precision of GPS navigation simulator remarkably.By using existing research achievements,this paper applies the simulated data based on the highly precise model of spacecraft orbit to the procedure of system simulation for GPS navigation simulator,and analyses the simulation result.The result shows that the working performance of GPS navigation simulator is improved distinctly by the method introduced in this paper.This paper may provide a reference for the design and manufacture of simulator in the future.
