View angle statistics of aircraft airborne antenna to GEO satellites

This paper presents the statistics of antenna view angle from aircrafts to Inmarsat GEO satellites. In addition a parametric model is proposed to estimate the impact of aircraft attitude change (roll, pitch, and yaw) to the satellite antenna view angles. Without delving into the details of geometrical attitude modeling, it is shown that an accurate argument can be constructed on the impact of aircraft movements and banking maneuvers to the satellite view angle. The results are presented as statistics over global scheduled flights in one day period. The statistic results are discussed at the end of the paper, where their impacts to the overall system design are analyzed.
