摘　　要：全球定位系统的应用越来越广,已经成为人们日常生活中不可缺少的一部分,在移动通讯、交通以及汽车领域当中,定位显得尤为重要。不久的将来,全球定位系统的发展将不可限量。文章首先介绍了GPS的工作原理,并指出了AGPS与之的区别,接着根据OMA所提出的SUPL标准简要阐述了APGS定位的流程,最后重点讲解了用于辅助信息传输的RRLP协议。Nowadays there is a re＇owing concem of the assisted global positioning system, the usage of it comes down to lots of filed, People can find it in the filed of communication, traffic, motorcar. It will not be a lone time that there will be more development for the system. The text introduces the theory of GPS and point out the difference between A-PGS, and then expatiate the position measurement procedure based on the SUPL which is put out by the OMA, at last describes the RRLP protocol which in charge of the transport of assist data.
