摘要
耗资300 亿美元、历经了20 年才建成的 G P S 系统是继阿波罗登月计划和航天飞机计划之后的第3 项庞大空间计划,它从根本上解决了人类在地球上的导航和定位问题,使导航和定位技术发生了巨大的变化。本文正是以 G P S移动车辆定位系统中的集群通信为背景,建立系统的数学模型,进行计算机仿真,并根据仿真结果分析系统性能。
Following Apollo Project and Space Shuttle Project , the GPS system is the third large aerospace project,which costs 30 billion dollars and twenty years .It not only radically resolved the problem of human being's navigation and positioning on the earth., but also brought out great changes to the navigation and positioning technology. This paper, which is based on trunking communication in the GPS Mobile Vehicles Supervisory System, builds the math model, simulates on computer and analyzes the capability of the system according to the simulation results.
