Implementation Of Satellite Positioning Information Management System

With the maturity of satellite positioning technology and the popularization of mobile communication technology,SPIMS(Satellite Positioning Information Management System)is widely used in our daily life.However,there are following problems among most of the SPIMS in domestic market:(1)The mature applications of large enterprises are all designed and developed independently by the companies themselves,with different positioning modes and inconsistent data formats,which create obstacles for information exchange with each other,(2)Small and medium-sized enterprises deploy the system on an ordinary PC,the system performs poor and with low capacity,(3)Most systems with single-point positioning mode,so the positioning accuracy of the system is limited.The purpose of this project is to realize the SPIMS under the laboratory conditions.With the help of the Internet,the system can offer the service of positioning management of people or objects equipped with positioning terminals:the viewing of real-time positioning and history tracks.In this project,according to the design of the software system,the positioning chip configured by the positioning terminal can be GPS,Beidou or hybrid positioning system,along with the optional position differential function,which ensures data security while ensuring positioning accuracy.The software system is developed by cloud computing technology and the hybrid architecture of C/S and B/S.Deploying this system on an ordinary PC,companies can achieve large capacity and high performance.Companies or individuals can use the system directly only with positioning terminals,or they can further modify and customize it according to their own needs.It helps to reduce the cost of system development and maintenance,which is beneficial to the promotion of the system.The SPIMS is composed of a system service platform and a user operation platform.The system service platform includes four parts:database server,communication server,web server and business server.The database server served for data access to terminal information,terminal administrator information and satellite positioning information.The communication server is connected to positioning terminals and terminal administrators for two-way communication:receiving satellite positioning information from the positioning terminal and storing it in the database server after data processing;receiving terminal management instructions from the terminal administrator and distributing them to the positioning terminal after processing.The web server offers access services for resources of the user's operation platforn The business server provides service support for business logic to the user operation platform.The user operation platform consists of ordinary user operation platform and terminal administrator operation platform Ordinary users can obtain the functions of location management and map tools through the web pages or WeChat applets.Terminal administrators can obtain the functions of terminal management,location management and map tools by web pages.After testing,the SPIMS realized under the laboratory conditions has met the requirements of function and performance.It is hoped that this project will contribute to the nation and people's positioning information security,and help to promote the development of satellite positioning with the advantages of high precision and low cost.
