The Design And Realization Of The Vehicle Navigator

In recent years, with the development of national defense construction andmodernization, all kinds of modern electronic equipment has been widely used. Modernwarfare combat troops put forward higher requirements. How to familiar with theterrain more quickly, and occupy a favorable position, real-time control of combattroops position information, so as to obtain the initiative to become one of the pirorityamong prioirties.This thesis discusses in detail the design and realization of navigation satelliteposition technology based on GPS. The design adopts Cortex-A8kernel ARM processorS5PV210as the core, and design the embedded system hardware platform for thenavigator, and complete the customization of the Operating System and the devicedirver;The design adopts high performance MST717CPU to finishing the design ofdisplay unit which supports digital display; Adopting single-chip microcomputer tofinishing the design of Human-machine interface; According to the power supply thedemand of each unit, a power management unit is designed with DC/DC power chips.This thesis works focuses on the design and implementation of software process. Fromthe requirement analysis to the data structure definition, function module design andcode design. Followed is the introducing of the debugging process and debuggingresults.By actual loading in use by the user, the navigator has achieved all designedrequirements includes rapid positioning, information prompt, track management. Thenavigator has been in mass production and had created good economic benefits for theenterpirse.
