基于高频电路设计的原理，设计了GLONASS接收机的方案。电路分为信号放大、中频分离和相干载波产生这三个部分。主要使用了微波集成电路放大器BGA2001，高频滤波器TA0676A，宽带正交解调器AD8347和集成压控振荡射频合成器Si4123。设计出的接收机能够接收GLONASS L1信号。

GPS定位代码matlab GLONASS频道服务 ##简介众所周知，GLONASS与GPS不同，尤其是FDMA。 如果要使用GLONASS数据进行定位，导航，定时以及做其他事情（如电离层建模，对流层监视等），则需要首先确定24个GLONASS卫星的频率信道。 显然，GNSS接收器可以通过广播星历接收频道。 实际上，在处理数据时，我们不必每次都使用导航文件来计算卫星的频率。 因为只有在新卫星替换完卫星之后，频道才会更改。 程序已开发并在服务器上运行。 它可以遵循GLONASS的官方信息，并生成一个文件（glo.dat），该文件记录GLONASS卫星的频道。 该文件每2小时检查一次，并每天自动更新。 提供了一个开放源代码，用于计算GLONASS卫星的频率信道。 主程序包包含4个文件，包括README.md，Makefile，glo.dat和main.cpp。 另外，为此实现了其他4种语言（Matlab，Fortran，Python和C）。 ##### README.md您将对该频道服务有很好的了解。 ##### Makefile只需输入make即可编译程序。 ##### glo.dat使
