CHARACTERIZATION OF GLOBAL SATELLITE NAVIGATION SYSTEM, (GNSS), AND THE MOST IMPORTANT INDIVIDUALL SATELLITE SYSTEMS (GPS, GLONASS GALILEO)

Karol Gajdošík, Stanislav Ďurčo

Abstract

In this article I will characterize global navigational system, GNSS, and the most important satellite systems used for world-wide navigation. Satellite navigation systems, using satellites on orbital planes, are invaluable in user positioning. As of this day there are only fully operational only two GNSS systems: American GPS and Russian GLONASS. EU and ESA are developing and constructing European satellite navigational system Galileo, which is about to enter full capability in 2020, and should be most accurate of them all. In this article I describe these systems, their creation, segments and use.
