Indoor navigation system

V diplomski nalogi bom predstavil razvoj in rezultate testiranja aplikacije za navigacijo znotraj stavb. Razvoj sistema je obsegal uporabo Bluetooth oddajnikov dveh različnih ponudnikov ter uporabo sistema za urejanje aplikacij in prostorov IndoorAtlas z vnosom tlorisov nadstropij, izdelavo mobilne aplikacije za operacijski sistem Android, ki je obsegala, izdelavo uporabniškega vmesnika, integracijo programskega orodja IndoorAtlas, snemanje signalov v prostoru ter testiranje in iterativno izboljševanje aplikacije. Razvita aplikacija je v optimalnih pogojih omogočala lociranje uporabnika v krogu z natančnostjo polmera 1–1,5 metra in navigiranje med poljubnimi lokacijami v istem in različnih nadstropjih. Ugotovil sem, da so na uspešnost lociranja vplivali različni dejavniki. To so kvaliteta pokritosti signala na lokaciji, kvaliteta snemanega signala, propagacija signala in karakteristike naprave. Ocenjujem, da je opisani sistem primeren za uporabnike, kjer zadošča določitev lokacije na približno tri metre, zato je predstavljeni tip sistema primeren za uporabo v različnih javnih ustanovah in večjih centrih oziroma kompleksih povezanih stavb.In this diploma thesis I will present the development and testing of an indoor navigation mobile application. Development consisted of integration of two different brands of Bluetooth beacons and a content management system (CMS) for managing indoor navigation for mobile applications, made by IndoorAtlas, with a custom mobile application for Android, mapping the indoor location\u27s signals of interest and iterative improvements of the application as testing progressed. The developed application has achieved up to 1-1.5 meter accuracy and navigation between two points in the same or different levels of the building in optimal conditions. I have found that there are several different factors affecting the accuracy of indoor positioning. Those were quality of coverage of signals of interest on the location, quality of the mapped signal, signal attenuation, and device characteristics. The appropriate use cases for this type of system are those, where there is no need for accuracy higher than 3 meters This means that this system is appropriate for large public complexes such as public institutions, major centres and complexes of connected buildings
