[Abstract]:Now the navigation terminal based on Beidou satellite navigation system has been widely used in various industries and fields. At present, there are four navigation systems in the world: GPS system GLONASS system GALILEO system and Beidou Beidouu system. In the future, the average annual growth rate of the market size of navigation mobile terminals in China will be as high as 99%. However, the current situation of navigation mobile terminals in China is that more than 94% of the navigation mobile terminals on the market are using GPS technology, and the market share of Beidou satellite navigation system is less than 3% of the total market share of China. In recent years, our government and related science and technology departments are vigorously promoting and supporting the development of Beidou satellite navigation industry. On December 27, 2012, the relevant government developed and provided the civilian service of Beidou Satellite. The purpose of this thesis is to design, develop and implement a mobile terminal based on the civil service of Beidou satellite, which is based on the semi-open source operating system Android and combined with the BD-228 Beidou navigation module. And ensure that the user mobile terminal can receive navigation satellite positioning signals at any time, wherever in China. The main work of this thesis is as follows: This paper designs, develops and implements the hardware, driving layer and application layer of mobile positioning system. The ARM11 of the OK6410 development board is chosen as the processor, and the BD-228 module is used as the Beidou receiving module. The Android operating system is transplanted based on ARM, and the key core driver module is modified and written. This paper analyzes the NMEA0183 protocol, compares the GPS signal format with the Beidou location signal, and designs and implements the Beidou localization signal analysis module. Based on the protocol analysis module, the collected Beidou navigation location information can be parsed and transferred to the upper application. 3) this paper analyzes the structure of Android operating system, summarizes the execution flow of GPS positioning signal data transfer from hardware to GIS software, designs and implements the corresponding module by modifying the mode of driving module. The beidou positioning signal data and the GPS positioning signal data are transferred to the upper layer by the same flow, which is transparent to the upper layer and embodies the design idea of loosely coupling hardware module and upper application. 4) this paper designs and implements the middle graphical interface under Android system, and realizes the functions of locating and tracking based on the Beidou location module and the off-line map module. 5) this paper designs and implements the function of off-line map module, and based on the map coordinate transformation algorithm, the navigation location information is associated with the off-line map and displayed.
