基于流式处理技术的GNSS信号并行跟踪方法

A Parallel Method of GNSS Signal Tracking Based on Stream Processing Technology

提出一种基于流式处理器的导航卫星信号并行跟踪方法,实验证明新型并行算法相对于传统算法提高解算速度高达几十倍,使得软件接收机多通道跟踪多种卫星导航定位系统的多颗卫星信号成为可能.

A parallel tracking algorithm based on GPU computing is presented for GNSS signals. The experiments show that the speedup of the new method based on GPU is up to tens times than traditional algorithm based on CPU and it goes up with the increase of the number of tracking channels. The research shows that the multi-mode GNSS SDR receiver is becoming possible.
