半实物仿真试验中GPS接收机模拟器的设计

The Design of the GPS Receiver Simulator in Hardware-in-loop Simulation Experimentation

在半实物仿真试验的过程中,为了能够实时地向SINS提供GPS信息,采用工控机、光纤通讯卡、仿真计算机、RS232串口卡设计了GPS接收机模拟器。试验结果表明,GPS接收机模拟器的设计方法可行。GPS信息对SINS解算结果的修正效果较好。

During the hardware-in-the-loop simulation experimentation,in order to supply GPS message to SINS. Industrial control computer, optical fiber communication card,simulation computer, RS232 serial communication card are used in designing GPS receiver simulator.The result of experiment shows that the design method is feasible.The effect, GPS message revising SINS calculating result, is good.
