摘要
GPS定位与导航系统对于舰船的正常运行非常重要,也是舰船武器系统进行制导和定位的关键模块,由于GPS信号传输过程中易受到各类干扰因素的影响,导致信号精度下降,因此,研究GPS信号传输抗干扰系统成为一项热点。本文首先分析GPS系统的信号传输特性,利用滤波干扰抑制技术设计船舶的GPS信号传输抗干扰系统,并对该系统的性能进行分析和仿真。
GPS positioning and navigation system is very important for the normal operation of the ship, and it is also the key module for the guidance and positioning of the ship weapon system. Due to the influence of various interference factors in the process of GPS signal transmission, the signal accuracy decreases. Therefore, the research on GPS signal transmission anti-interference system has become a hot topic. This paper first analyzes the signal transmission characteristics of GPS system, designs the anti-jamming system of GPS signal transmission of ships by using filter interference suppression technology, and analyzes and simulates the performance of the system.
