Measurements and Model for the Satellite-to-Aircraft Channel in L-Band

Abstract

Wireless radio transmission from a satellite based emitter to a receiver located on a aircraft is of interest for many applications such as passengers internet access, air traffic management or positioning by global navigation satellite systems (GNSSs). Especially, the last two applications listed are related to safety-of-life functionality that requires accurate channel models for software based system testing. State-of-the art channel models for the satellite-to-aircraft case lack of accuracy in terms of modeling all propagation impairments. In this contribution, we describe the airborne experiments using Global Positioning System (GPS) signals and the data evaluation. A preliminary channel model is presented.
