摘要
详细介绍了GPS模拟器在GPS/INS组合导航系统半实物仿真试验中的应用。借助该GPS模拟器,某系统在仿真试验中对GPS/INS组合导航软、硬件系统进行了全面的考核,并在试验过程中发现了某款GPS接收机动态下速度定位不准确问题,然后根据通过模拟器测得的数据确立了一种补偿方案。经实物导航考核验证,通过GPS模拟器获得的试验数据可信。
This paper describes the application of GPS simulator during the hardware-in-the-loop simulation in the GPS/INS integrated navigation system. With the help of the GPS simulator, a fatal deficiency that the GPS receiver can not locate correctly in the dynamic environment is detected. Then a compensating scheme is established based on the data that acquired from the simulation. The data from the experiment with the help of the GPS simulator are creditable.
