云计算技术在大规模基准站网中的应用

Aiming at the problem that the storage and computing efficiency of conventional personal computers (PCs) is low and cannot meet the requirements for efficient data computing of large-scale global navigation satellite system (GNSS) reference station networks, the use of cloud computing technology to achieve efficient computing is proposed: A computing platform is built using cloud computing technology, and the GAMIT/GLOBK software system is installed for large-scale GNSS reference station network data processing, and a comparative analysis is carried out with the calculation on a PC. The results show that when more than 6 tasks are run simultaneously on the cloud computing platform, the efficiency is significantly better than that of a PC; and as the number of tasks increases, the efficiency is significantly improved. When the number of files opened by the software reaches the maximum load, the cloud computing platform still operates stably and normally, and the calculation results are correct and reliable.

针对常规个人计算机(PC)存贮与计算效率低,无法满足大规模全球卫星导航系统(GNSS)基准站网高效数据计算要求的问题,提出利用云计算技术实现高效的计算:采用云计算技术搭建计算平台,安装GAMIT/GLOBK软件系统进行大规模GNSS基准站网数据处理,并与PC机解算进行对比分析。结果表明:云计算平台上同时运行6个以上任务时,效能明显优于PC机;且随着任务数量的增多,效能显著提高,当软件打开文件数量达最大荷载时,云计算平台仍稳定正常运行,且计算结果正确可靠。
