KAILOS based on a variety of technologies and solutions spanning indoor and outdoor integration aims to provide a navigation system
KAILOS hybrid positioning engine is flexible and scalable as it can utilize various signals and sensors such as GPS, WLAN, Bluetooth, magnetometer, accelerometer and gyroscope for positioning.
In order to enhance the accuracy and reliability of positioning, the KAILOS positioning engine integrates various filters like signal filter, Kalman filter, delay filter and map matching filter. In addition, the KAILOS engine adopts a very unique similarity measure, which distinguishes it from other positioning systems.
The most prominent feature of KAILOS is its automated radio map construction capability. KAILOS has the capability of building radio maps automatically using data collected from users through crowdsourcing. KAILOS divides an indoor area into moving and staying areas and then uses slightly different approaches for building radio maps at each area.
Allies, stairs, lobbies are the spaces of moving areas. For the moving area, the KAILOS aligns, assembles fingerprint sequences to merge them into simple a graph, and then match the graph with the floor plan of a building for the location tagging of fingerprints.
Staying area includes home, office, and store that are usually used for point of interests (POIs) of positioning service. The KAILOS constructs radio maps for those areas by utilizing the address information of users. The fingerprints collected at night time are considered to be collected at the home of users, and the location of the home is tagged as collected location of fingerprints.
