GNSS合作定位研究综述

A Survey of GNSS based Cooperative Positioning

针对普遍使用的定位方式无法满足日益增长的定位需求的问题,人们借鉴移动机器人定位中合作定位(Looperative Positioning)的思想,提出一种新的GNSS(Global Navigation Satellite System)定位策略——GNSS合作定位。详细介绍了GNSS合作定位发展历史、分类、基本思想和算法基本环节等。相关仿真实验表明,这种新型定位策略定位精度能够达到甚至超过目前广泛使用的AGNSS(Assisted GNSS),且所需定位时间更短,证明这种定位技术的可行性。

The widely used positioning methods fail to satisfy the increasing demand of users. Researchers develop a new GNSS Positioning strategy, called GNSS Cooperative Positioning, based on the concept of Cooperative Positioning （CP） in acquiring real-time positioning information of mobile robots. An in-depth survey of GNSS Cooperative Positioning, including its history, types of CP, basic idea, key steps of algorithm is presented in this paper. Current research results of GNSS CP show that this new positioning strategy gets equal or better positioning accuracy with less time cost compared with Assisted GNSS （AGNSS）.
