In this paper, a data classification method for analyzing the aspects of Signal-to-Noise Ratio (SNR) for Global Navigation Satellite System (GNSS) in real conditions is introduced. Different parts of measured environments and the orbital information of satellites are used as criteria for data classification. It consists of: 1) taking fish eye images of measured routes; 2) dividing measured environments...
In this paper, the differential total atmospheric attenuation and differential total losses are investigated in the case of spectral co-existence of GEO and MEO constellation satellite communication systems. In order to use larger bandwidth in the next generation satellite communication systems, many radio systems may share the same spectrum. Due to the high interest on MEO constellation systems to...
The usage of Fade Mitigation Techniques (FMT) is mandatory for satellite communications operating over 10GHz once the atmospheric propagation effects get severe with the increase of the frequency-band. Site Diversity (SD) and Orbital Diversity (OD) are two effective techniques to mitigate rain attenuation. Considering an operation at Q-band (40GHz) both these schemes are preliminary investigated:...
