Signal monitoring as a part of maintenance of navigation support system in civil aviation

Abstract

This paper gives an overview on some chosen aspects of monitoring signal in case of system performing abilities. Nowadays, in civil aviation, there is a focus mainly on satellite systems which are often called the future of navigation. Global Navigation Satellite System (GNSS) is not able to operationally work without any support system. One of them is EGNOS (European Geostationary Navigation Overlay Service)
