GPS伪卫星射频捷变收发器时分多址(TDMA)二进制相移键控(BPSK)为了搭建用于室内定位的伪卫星室内定位系统,设计了一个伪卫星用于发射模拟GPS卫星定位信号.从伪卫星的硬件结构的角度详细说明了该伪卫星的各部分硬件组成以及相应的功能.该伪卫星使用了AD9361射频捷变收发器将时钟小数分频,数模转换,信号调制,上变频融为...
The pseudolite utilizes the AD9361 RF agile transceiver to integrate functions of converting the clock fraction frequency divi- sion,digital-analog conversion,signal modulation and the frequency conversion,which simplifies the hardware structure of the pseudolite. Then,the specific struct...
