| 摘 要： | 传统的基于行业用户需求而建立的集中式高精度导航定位服务模式在可靠性、可扩展性以及服务多样性等方面已无法满足大众用户的精密定位需求。结合云平台技术,提出了云定位的概念,通过综合管理和整合各类定位资源,实现多种定位手段的资源共享、技术融合和优化配置。给出了云定位的架构图,并讨论了GNSS网络RTK,GNSS广域精密定位,Wi-Fi定位,通信基站定位等多种手段在定位云上的综合和服务实现。云定位在可扩展性、可靠性、系统维护成本以及用户使用灵活性等方面都具有传统的精密定位服务模式所无法比拟的优势;通过云定位,用户不仅可以获取各类精密定位服务,还能实现多种定位资源的优化配置,定制个性化的应用;为精密导航定位的大众化普及提供有效的商业模式和技术途径。

| Abstract: | Traditional centralized high-precision navigation and positioning services cannot meet thepublic users'demand for reliability,scalability and service diversity.This paper describes cloud posi-tioning,and the way in which various positioning resources are managed and integrated comprehen-sively to optimize technology convergence and resources sharing,based on cloud technology.We pres-ent the cloud positioning,framework and discuss the realization of several traditional positioning tech-nologies through the cloud positioning platform,i.e.,GNSS Network RTK,GNSS wide area precisepointing positioning,Wi-Fi positioning,communication base-station positioning and others.We arguethat,compared with the traditional technologies,cloud positioning has more advantages in scalability,reliability,the maintenance cost and feasibility.Using the cloud positioning platform,not only canusers enjoy various high precision positioning services,but also optimizes allocation of resources toprovide personalized services.An efficient business model and technical approach will allow for thepopularization of precise navigation and positioning services. |
