摘要
针对国内导航系统与授时系统的发展现状,将两个系统合理地结合在一起并以STC12C5A单片机作为整个系统控制单元,设计出的导航授时服务系统成本低、功耗低。给出了系统的硬件设计和软件流程,同时介绍了上位机软件的模块化设计思想。经过测试,该系统可以在户外或室内对运动的载体实行导航定位,当系统结合计算机运行时能对计算机进行授时。
According to the domestic development of navigation system and time service system, the system is designed based on microcontroller STC12CSA with the characteristics of low-cost and low power consumption. The paper introduces the principles of hardware design and software flow chart, and also introduces a modular design of PC software. The system can carry out navigation both indoor and outdoor for moving objects and time service for computer.
