基于云计算技术的新一代GPS卫星定位系统设计

摘要

针对传统的单层卫星网络结构在通信过程中存在着错位通信、时延指标过高、网络阻塞概率大、造成的定位误差较大缺陷,为满足高实时性的要求,运用多层协同云计算技术的卫星错位测量设计方法消除误差；通过多层卫星网络设计方法协同云计算技术,配合定位中错误补偿设计云端算法,最大程度上消除卫星在协同工作中出现的死角,定位偏差等弊端；利用模拟实验对卫星网络各项指标进行测量,证明该方法较好地消除了多层网络中出现的时延和定位误差较大的弊端,为新一代的卫星定位系统设计提供思路.%In traditional single satellite network structure in the communication process there are a dislocation communication, time delay index higher, and network congestion probability, the positioning error caused by large defects, to meet high requirement of real — time, used in multi — layer cooperative computing clouds of dislocation satellite technology measurement system to eliminate the error. Use multilayer satellite network design method collaborative computing clouds technology, fit positioning error compensation algorithm design of clouds, the maximum extent in collaborative work to eliminate satellite appeared in a corner, the disadvantages of locating errors. Using simulation experiments of satellite network index measuring experiment, proves that this method is good to eliminate the multilayer network delay and positioning error appear larger abuses, for a new generation of satellite design to provide ideas.
