This paper presents insights about schemes required to provide ultra-precise positioning services for multifarious environments. It describes positioning services and their requirements, and divides the services into “living convenience” and “productivity improvement”, and the requirements into “positioning quality” and “system efficiency”. It also presents the current accuracy levels, technical challenges, and research directions of positioning schemes that are based on satellite/communication system, image, ray-tracing, and fingerprint. Ultimately, this paper presents scenarios and solutions that provide 10cm-level positioning accuracy for both outdoor and indoor environments.
