A Concept for GNSS Interfence Monitoring

Felix Butsch

Abstract:	Electromagnetic interference to satellite navigation re-ceivers being used in aviation is safety critical and an eco-nomic risk. For this reason signals occurring in the fre-quency range of GPS and GLONASS should be monitored. The paper presents a requirement study for a GNSS interference monitoring station. The study is based on the experience gained by susceptibility tests of GPS and GLONASS receivers and field measurements near German airports. After a description of the measurement principle, the requirements for the necessary equipment are discussed. Furthermore the automatic evaluation of the signal spectrum for the assessment of its impact is de-scribed. Finally a measurement setup for an interference monitoring station is proposed.
