The article depicts the indoors positioning technology and user mobile positioning devices. It describes the possibilities of computer technology of indoors positioning of the device when navigating the user through the territory of tourist sites, which are castles, museums, galleries and architectural monuments. Popular positioning technology, which is a GPS (Global Positioning System) is not fully operating in indoor environment and buildings. The most popular alternative information technologies of positioning in a confined spaces are now the Wi-Fi, iGPS, RFID, NFC and technology, based on the relevant processing of visual images. The article shows the analyze of methods of Wi-Fi positioning, their advantages and disadvantages in the context of use in different types of indoor environment. The article shows the defined prototype of technologies of positioning and navigation of tourists which the authors propose to use in the creation of intellectual problem- oriented system “Mobile information assistant of the tourist” (MIAT). The algorithm of positioning of the mobile devices (smartphone, tablet) in a complex tourist sites is presented in the article. The algorithms is based on Wi-Fi triangulation and fingerprints and uses COST231 multi- wall model for user device positioning.
