Research On Field Operation Real Time Positioning Communication System

In order to adapt to the need of military transformation and modernization construction, the author studies how to realize the technology about field operations real time position and communication system, which is based on the combination of the exiting shortwave communication system, OPS and GIS.Firstly, the thesis introduces the development and application of GPS, discusses the basic makeup and position principle of GPS, and analyses the error of position. Then it demonstrates the scheme of realizing the transmission of field operations real time position data, based on the shortwave communication system, and puts forward the hardware architecture, software makeup and transmission method of the position data. After that, it studies the processing method of electronic map and the position data, including the data structure, dada model, data making method, graphic operation and data query method of electronic map. Finally, it designs the software of electronic map and accomplishments the software debugging.
