GNSS信号接收机是GNSS导航卫星的用户设备，是实现GNSS卫星导航定位的终端仪器。它是一种能够接收、跟踪、变换和测量GNSS卫星导航定位信号的无线电接收设备，既具有常用无线电接收设备的共性，又具有捕获、跟踪和处理弱达3.5E-16W～2.5E-17W卫星微弱信号的特性。为此，GNSS信号接收机的构件必须满足这种捕获、跟踪和测量GNSS信号的需求。
GNSS信號接收機是GNSS導航衛星的用戶設備，是實現GNSS衛星導航定位的終耑儀器。它是一種能夠接收、跟蹤、變換和測量GNSS衛星導航定位信號的無線電接收設備，既具有常用無線電接收設備的共性，又具有捕穫、跟蹤和處理弱達3.5E-16W～2.5E-17W衛星微弱信號的特性。為此，GNSS信號接收機的構件必鬚滿足這種捕穫、跟蹤和測量GNSS信號的需求。

The GNSS signal receiver is GNSS user equipment for satellite navigation and the terminal equipment for realizing GNSS satellite navigation/positioning. It is the radio receiving equipment that is able to receive, process, track and measure the GNSS navigation signals. It has not only the common performance of the radio receiving equipments, but also the characteristic performance for acquiring, tracking and surveying the weak satellite signals of 3.5E-16W~2.5E-17W. For this reason the structural components of GNSS signal receivers must meet the needs to capture, track, and measure the GNSS signals.
