This paper presents KAIST indoor locating system (KAILOS), which aims to provide a global indoor positioning service based mainly on Wi-Fi fingerprints. KAILOS integrates various techniques and tools which are categorized into three components in large: KAI-Map, KAI-Pos, and KAI-Navi. KAIMap comprises crowdsourcing indoor maps and radio maps. KAI-Pos is the positioning system installed on KAI-Map. KAI-Navi is an in-and-outdoor integrated navigation system installed on KAI-Map and KAI-Pos. A positioning technology stack is also introduced in this paper, and the components of KAILOS are presented in the framework of the positioning technology stack.
