We have developed a smartphone-based indoor localization platform on cloud named Jupiter. Jupiter uses a self-developed indoor positioning technology, which uses radio frequency (RF) signals and sensor measurements measured by a smartphone. There are two steps to using the platform. The first is the establishment of infrastructure in the area where the service is desired. Infrastructure construction includes both TJLABS’ Bluetooth beacon installation and radio map production for position calculation. Since the developed technology uses a method different from the existing triangulation and fingerprinting methods using Bluetooth, all infrastructure construction costs including time and money have been dramatically reduced. It can be implemented so that the service can be provided within a day in a place the size of the underground parking lot at COEX located in Seoul. The second is to register users to receive services. Our technology creates movement and spatial data using the aforementioned values measured in the smartphone and transmits it to the cloud. These tasks are included in both the SDK developed with Android and iOS Native, and by providing them, the user’s inconvenience is minimized. Users can request their position when they want or use them in the form of taking their position that is being continuously tracked. Jupiter’s engine is implemented on the cloud and can provide sufficiently reliable position results within 0.3 seconds of a request. The accuracy is about 1~5m in general.
