Keywords: navigation; hyperbolic systems; radiolocation; AEGIR; TDOA.

Abstract:
Humans have always wanted to determine position in an unknown environment. At the beginning methods were simple. They were based on the observation of characteristic points, in the case of shipping additional observations of the coastline. Then came navigation based on astronomical methods (astronavigation). At the beginning of the XX-century a new way of determining the current location was developed. It has used radiowave signals. First came radio-beacons. Then ground-based systems came. Currently satellite systems are being used. At present, the most popular one is Global Positioning System (GPS). This system is fully controlled by the Department of Defense, and only the U.S. forces and their closest allies have been guaranteed accuracy offered by the system. Armies of other countries can only use the civilian version. This situation has engendered the need for an independent radiolocation system. This article describes the construction and operation of such a technology demonstrator that was developed at Gdansk University of Technology. It was named AEGIR (according to Norse mythology: god of the seas and oceans). The main advantage of the system is managing without the chain organization of the reference stations, which work now with each other asynchronously. This article demonstrates the functionality of such system. It also presents results and analysis of its effectiveness.
