卫星导航接收有源天线负责接收GPS、GLONASS和BD-2(B1频点、B3频点)卫星信号,并将信号滤波、放大,为接收机提供GPS/GLONASS/BD-2信号,送入接收机进行定位处理,用于卫星导航和测量系统测量定位。有源天线是将低噪声放大模块和天线集成为一体的电气系统,相对于传统天馈系统,有源天线取消了天线与低噪放之
The satellite navigation receiving active antenna is responsible for receiving satellite signals of GPS, GLONASS and BD-2 (B1 frequency points and B3 frequency points) and filtering and amplifying the signals to provide GPS / GLONASS / BD-2 signals to the receivers for receiving Machine positioning processing, for satellite navigation and measurement system measurement and positioning. The active antenna is an electrical system integrating the low-noise amplification module and the antenna. Compared with the conventional antenna-fed system, the active antenna cancels the antenna and the low-noise amplifier
