Research On GPS Navigation System With ARM11

GPS satellite navigation system can be used to positioning, navigation and speed measurement.and has global, all-weather’s features has become increasingly widely used in all walks of life. With the rapid development of automobile industry, people’s living standards,GPS car navigation systems in the car audio and video have been widely used.GPS car navigation system is a set of navigation and audio-visual entertainment solutions. This paper describes the based on the ARM11and WINCE6.0GPS navigation system structures. Focus on the following four elements:1, GPS navigation systems and car DVD systems how to cooperate with each other. Through the analysis of car DVD systems, and reference implementations on the market mainstream, this part gives the GPS navigation system and car DVD system how the hardware and software to cooperate with each other.2, Car DVD with GPS navigation systems implementation. Based on the analysis of vehicle GPS navigation system, the paper introduces the SIRF PRIMA chip based on ARM11core of the hardware architecture, introduced a navigation system module functions, such as active antenna, RF processing, storage, audio, video, power management.3, Navigation system software architecture. The paper through to the car GPS navigation system, introduced a navigation system software framework.4, GPS navigation performance evaluation. Focuses on the GPS performance in all environments and the comparison of other GPS solutions on the market.Based on all the above research results, the test results are given. At the end of the article, the system undertook summing up, pointed out the deficiency of the system, puts forward the improving methods, and prospects the future development direction.
