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.
