研究并设计了一种授时定位设备,该设备不仅具备北斗、GPS卫星导航系统移动终端的各种功能特性,而且结合了B码、外校时等辅助授时功能,除此之外,还实现了高精度自守时功能.在硬件设计上,采用嵌入式ARM体系结构进行了经济型设计,同时充分考虑了可靠性和维修性设计；在软件设计上,采用嵌入式Linux操作系统,在完成功能性设计的同时,实现了多模授时方式的灵活切换,并提供了设备两种级别的故障诊断测试,极大地提高了设备的可靠性和维修性.%The design of the timing and positioning of equipment! Not only have the Beidou. GPS satellite navigation system features a variety of mobile terminals, and a combination of B code, outside the school when the timing and other auxiliary functions, in addition, also high accuracy from punctuality function is achieved In hardware design, embedded ARM architecture using the economic design, take full account of the reliability and maintainability design; in software design, embedded Linux operating system, the completion of the design while achieving a multi-mode timing flexible way switch, and offers two levels of equipment failure diagnostic test, which greatly improved equipment reliability and maintainability.
