GNSS-SDR学习笔记0-- GNSS-SDR开源软件接收机介绍_软件定义的接收机

GNSS-SDR provides an interface to different suitable RF front-ends and implements all the receiver chain up to the navigation solution. Its design allows any kind of customization, including interchangeability of signal sources, signal processing algorithms, interoperability with other systems, output formats, and offers interfaces to all the intermediate signals, parameters and variables. The goal is to write efficient and truly reusable code, easy to read and maintain, with fewer bugs, and producing highly optimized executables in a variety of hardware platforms and operating systems. In that sense, the challenge consists of defining a gentle balance within level of abstraction and performance. GNSS-SDR runs in a personal computer and provides interfaces through USB and Ethernet buses to a variety of either commercially available or custom-made RF front-ends, adapting the processing algorithms to different sampling frequencies, intermediate frequencies and sample resolutions.
