Description
The attenuation time together with the Complementary Cumulative Distribution
Function of attenuation values play a vital role in the design of communication systems.
Passengers on-board during flight can be connected to the internet either via satellite or earthstation
depending on the nature of the flight. For long distance flight, this internet connectivity
is provided through satellite when the aircraft is flying at the upper troposphere. However, the
satellite-aircraft link is subject to attenuation due to the troposphere. A model to characterize
the channel has been proposed. In particular, a methodology for the synthesis of attenuation on
aircraft-satellite is given by ITU-R P2041 recommendation. However, it has been shown that
the impact of tropospheric parameters such as rainfall, cloud, gases etc. On the satellite-aircraft
link at different frequencies are insignificant (i.e decreases with height) on the upper
troposphere since the aircraft is flying (about 12 km) above the rain height (5 km). The
findings will be useful for researchers, scientists and the aviation industries in planning, design
and establishing link budget for aircraft-satellite path.
