Design and Implementation of embedded multi-module timing and orientation device

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.
