摘要
本文对高性能GNSS软件接收机技术进行了研究，首先给出了其总体结构设计，并对其关键技术进行了讨论；然后采用Matlab语言实现了一个12通道的GNSS软件接收机；最后利用采集的36秒钟数字中频信号验证了该软件接收机设计的正确性，并给出了软件接收机的捕获、跟踪和定位解算结果。
In this paper, the technology of high performance GNSS software - defined receiver is investigated, and the overall structure design diagram is given, and the key techniques are discussed. The GNSS software receiver with 12 channels is realized in Matlab. Finally, with the collected 36s IF signals, the correctness of receiver algorithms is validated, and the acquisition, tracking and positioning results are presented.
