Navigation Satellite Signal Acquisition Playback

navigation satellite signal playback device adopts the satellite signal acquisition and playback equipment independently developed by Beijing Naiwei Times Technology Co., Ltd. with independent intellectual property rights. It is a radio frequency signal high-fidelity recording and playback equipment with built-in acquisition and playback antenna and lithium battery power supply. It can collect the navigation signal of the actual scene without any external cable, and repeat the playback in the laboratory for many times, build indoor real signal test scenarios. With the help of high-precision calibration system, the recording test system based on navigation signal acquisition and playback can also realize the quantitative test of the dynamic positioning accuracy of navigation equipment. It is mainly used in the design process of receiver function verification, product function verification in the production process and so on.
