[Abstract]:With the coming of 3G mobile Internet era and the continuous development of embedded hardware devices, mobile intelligent terminal devices, represented by Android mobile phone operating system, have gradually become the focus of attention. The Android operating system is developed based on open source Linux kernel. People can not only develop upper application programs based on Android system framework, but also realize Linux kernel driver porting and middleware development according to specific hardware devices. GPS positioning systems are widely used in people's lives, especially in cars, ships, mobile phones, tablets and other devices. Therefore, it is of great significance to study the implementation of GPS positioning system based on Android system. This paper introduces the research and implementation of GPS positioning system based on 3G Internet of things experiment platform based on Android operating system. This paper introduces the development process and realization principle of GPS positioning system, and specially designs and implements the GPS hardware module based on 3G Internet of things experiment platform. The realization steps of this paper are as follows: 1) introduce the whole frame of Android system, expound the history and basic principle of GPS system technology. From the design and function analysis of the 3G Internet of things experimental platform processor, memory, LCD display module, touch screen, audio, Power module and other hardware modules. 2) expatiate the construction of software compiling environment based on 3G Internet of things experimental platform, the compilation and writing process of Android system. 3) analyze the implementation of GPS positioning system based on Android system. This paper mainly introduces the GPS driver based on 3G Internet of things, the transplantation of GPS hardware abstraction layer and the realization of GPS JNI layer code. 4) testing the GPS positioning system and calculating the longitude and latitude of the current position. And use the Google map to show the current location. Finally, based on the 3G Internet of things experiment platform, the implementation process of GPS positioning system is summarized and evaluated, and the advantages and disadvantages of the whole system design process are explained, which points out the direction for further research.
