③ 摘要
GPS衛(wèi)星模擬器試驗(yàn)設(shè)施是用來(lái)校驗(yàn)全球定位系統(tǒng)接收器和增強(qiáng)系統(tǒng)的軟件和硬件的。一般情況下，它們包括衛(wèi)星信號(hào)模擬器，差分放大模擬器和仿真器的接口。所有的測(cè)試運(yùn)行實(shí)時(shí)需要大量的硬件和人力資產(chǎn)。起初，動(dòng)態(tài)情況下的模擬必須設(shè)計(jì)并存儲(chǔ)在模擬器控制計(jì)算機(jī)。這種情況下指定好所有有關(guān)的因素，包括GPS接收器的軌道，人造衛(wèi)星的位置，信號(hào)功率和波形，環(huán)境因素包括傳播錯(cuò)誤和干擾的影響。一般情況下，在實(shí)際測(cè)試情況前，要完成大多設(shè)備安裝和校準(zhǔn)。此外，衛(wèi)星模擬器及控制設(shè)備的費(fèi)用昂貴，通常需要100萬(wàn)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.
