摘要
全球定位系统是目前远程导航和定位最通用的方式,具有高精度、全天候、高效率、多功能、操作简便等显著特点。本文根据GPS-OEM的工作原理和通信协议,结合FPGA硬件特点设计了基于NIOS II的GPS数据采集存储与显示电路,给出了硬件设计和软件设计具体流程。该电路能够广泛应用于海、陆、空移动物体的导航、导弹制导、大地测量和工程测量的精密定位,具有一定的工程应用价值。
With advantages of high precision,high efficiency,multi-function,all-weather availability,simple operation,Global Positioning System（ GPS） has been widely used in remote navigation and positioning. Based on analyzing the working principle and communication protocol of GPS-OEM,this paper designs a GPS data acquisition and display system based on FPGA of NIOS II series,and puts forward its implementation method on both hardware and software.This system can be used in aircraft navigation,missile guidance,geodetic engineering and precision measurement,having certain engineering application value.
