Direction Finder for Indoor Positioning

Abstract

Generally, getting precision position information is very important in industry, especially avionics as well as air traffic, also in automotive, pedestrian etc. There are a lot of navigation methods to get position information and every use has its own verified methods. Particularly autonomous devices depend on a getting of accurate positional information in each time. Currently, the indoor positioning is solved in many applications and the main task is a position determination of device, object or people inside buildings. These systems usually use wireless systems based on radio waves, lights, impact sensors etc. Basic principles are typically based on known principles as the time difference of arrival, direction finding, triangulations etc. This paper deals with the implementation of aeronautical navigation methods like instrument landing systems into the indoor positioning system with UHF beacon.
