At present the most popular radiolocation 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 ar-mies of countries other than the U.S.A. This situation has engender a need for development of an autono-mous, ground-based radiolocation system, based on the hyperbolic system with spread spectrum signals. This article describes the construction and operation of such a system technology demonstrator which was devel-oped at the Technical University of Gdansk. It was named AEGIR (god of the ocean in Norse mythology). This paper presents preliminary results and analysis of its effectiveness.
