Abstract
This paper studies the application of simple GPS positioning information display system based on single chip computer. Firstly, the working principle of single chip microcomputer and the basic concept of GPS positioning technology are introduced, and the importance of information processing and communication protocol in GPS positioning system is discussed. Then, the application of the system in many fields such as vehicle positioning and tracking, mobile intelligent device positioning, UAV navigation, outdoor sports and exploration is described in detail. However, in the process of application, the simple GPS positioning information display system also faces the problems of limited positioning accuracy, unstable signal reception, high energy consumption and high system cost. In order to solve these problems, this paper puts forward a series of optimization measures. By adopting multi-mode positioning technology, optimizing antenna design and layout, and optimizing signal processing algorithm, the positioning accuracy can be effectively improved. At the same time, optimizing antenna design, selecting high sensitivity GPS receiver chip and enhancing anti-interference capability can significantly enhance signal reception capability. In order to reduce the energy consumption of the system, this paper puts forward the design of low power consumption single chip microcomputer, the switching strategy of system working mode and the optimization of power management. Finally, system costs can be reduced by adopting cost-effective components, designing modularity and scalability, and utilizing open source software and hardware. In summary, the research of this paper not only helps to improve the performance of simple GPS positioning information display system based on single chip microcomputer, but also provides a valuable reference for the further development of related fields.
