③ 摘要
GPS卫星模拟器试验设施是用来校验全球定位系统接收器和增强系统的软件和硬件的。一般情况下，它们包括卫星信号模拟器，差分放大模拟器和仿真器的接口。所有的测试运行实时需要大量的硬件和人力资产。起初，动态情况下的模拟必须设计并存储在模拟器控制计算机。这种情况下指定好所有有关的因素，包括GPS接收器的轨道，人造卫星的位置，信号功率和波形，环境因素包括传播错误和干扰的影响。一般情况下，在实际测试情况前，要完成大多设备安装和校准。此外，卫星模拟器及控制设备的费用昂贵，通常需要100万美元。


GPS satellite simulator test facilities are used to checkout the software and hardware of GPS receivers and their augmentation systems. In general, they include satellite signal simulators, differential augmentation simulators and interface emulators. All testing is run in real time and requires considerable hardware and human assets. Initially, the dynamic scenario to be simulated must be designed and stored in the simulator control computer. This scenario specifies all relevant factors including the trajectory of the GPS receiver(s), the satellite constellation, the signal power and waveforms, environmental factors including propagation errors, and jamming effects. In general, there is considerable equipment setup and calibrations that must be performed prior to actually exercising the scenario. In addition, the satellite simulator and control equipment are expensive resources typically costing on the order of one million dollars.
