Ground-based radiolocation system - AEGIR

At present the most popular navigation system in the world is Global Positioning System (GPS). As it is managed by the Department of Defence of the U.S.A., there is always the risk of the occasional inaccuracies or deliberate insertion of errors, therefore this system can not be used by secret services or armies of countries other than the U.S.A. This situation has engender a need for development of an autonomous radiolocation system. This article describes the construction and operation of such a system technology demonstrator which was developed at the Gdańsk University of Technology (GUT). It was named AEGIR (god of the ocean in Norse mythology). This paper presents results and analysis of its effectiveness.
