GPS
- 通常GPS定位信息接收系统主要由GPS接收天线、变频器、信号通道、微处理器、存储器以及电源等部分组成。由于GPS定位信息内容较少,因此多用RS-232串口将定位信息(NEMA0183语句)从GPS接收机传送到计算机中进行信息提取处理。-GPS location information is usually received by the GPS receiver system antenna, frequency converter, signal channel, microprocessor

- 这是一个模拟GPS接受机的程序, GPS数据由给定文件来模拟,只要定时读取数据并分析各成分 的含义,就可以确定卫星的位置。 本例主要用来演示不同坐标系的转换。 同时还有文件信息如何提取并显示-This is a simulation of the process GPS receivers, GPS data from the given file to simulate, as long as data from time to time to read and analyze
GPS
- 目前,GPS系统不仅在全球的应用越来越广泛,而且在最近的几场局部战争中也起到了非常重要的作用,因此有必要对GPS的对抗进行研究。本文首先简要介绍了GPS系统的基本组成,然后针对各个组成部分提出了针对性的对抗措施,并重点探讨了对GPS用户接收系统的干扰方法。-At present, the GPS system not only more and more popular around the world, but also played a very important role in the
