摘　　要：针对车载和机载卫星导航系统的数据采集问题,采用以现场可编程门阵列(Field Programmable Gate Array,FPGA)为平台的GPS导航系统数据解析方案。该设计以NMEA-0183协议的数据格式为基础,循环判断报文头、定位状态、校验位和结束位标志,根据逗号计数器的值决定提取所需要的导航信息,直至完成正确的解析。用Verilog HDL硬件描述语言完成了代码设计,并在FPGA内部生成硬件电路。仿真与硬件测试结果均表明该设计可提取导航系统中的定位信息。For the problem of NMEA-0183 protocol parsing in the vehicle and airborne navigation system,an GPS navigation system data paring scheme based on Field Programmable Gate Array （FPGA） is presented.The design based on the data format of NMEA-0183 judges message header, stationary state,parity and stop bits. It extracts the navigation data until it achieves the correct resolution according to the comma counter value.It uses Verilog HDL hardware description language to complete the code design and generates the hardware circuit in FPGA.The simulation and hardware testing results show that the proposed design is simple and flexible,and can be easily extracted the location in the navigation system information.
