Design And Research Of Embedded Navigation System

With computer becoming more applicable and portable, and the emergence of various embedded devices, Navigation System, using the embedded technology into the traditional geographic information services, changed the traditional service mechanism revolutionarily. It seamlessly integrates human and the real and digital world. It changes the way of interaction between human and the real digital world. Integrating the embedded, global positioning, geographic information and other technologies, embedded navigation system achieved real-time positioning and mobile computation. Working on various mobile devices such as the smart phones, PDAs, it meets the needs of users of different levels. It can be used in many fields such as various outdoor operations map browsing, on-board navigation, outdoor industrial and agricultural data collection, outdoor facilities maintenance. Embedded Navigation System is of high value to improve the quality of social services and the living standards of human.On the other hand, with the voice becoming an effective input, a design of a new embedded navigation system based on voice input is proposed in this paper. First analyze the research on the navigation system and the progress of the status to explore significance of this paper. Then analyze the positioning process with the global satellite positioning system and its receiver; and explore the development of GIS and its application on the electronic maps. After analyzing the development methods and solutions of embedded navigation systems, designed the overall logic structure of navigation system and workflow navigation engine; studying the Windows CE embedded system and its emulator and MapX Mobile GIS control, constructed platform; detailed designed, programmed and implement a prototype of navigation system, named"Navigator", which achieved expected effect.
