Impact analysis of navigation signal in the radio astronomy band

Abstract

The band 1610.6-1613.8 MHz is used by the radio astronomy (RA) community in order to receive, measure and study the radio from star for the formation of protostars and the initial stages of star formation. The observation of the radio signal is very sensitive to the interference environment present in the band since the investigated signal is received with a very low power. In this paper, according to the International Telecommunications Union recommendations and characteristics of navigation system signal and constellation, a simulation is made which calculates the power rejection of the navigation signal in RA band. The result of this paper can provide a reference for the design of payload filter and the analysis of system compatibility. © 2013 Springer-Verlag Berlin Heidelberg.
