Abstract: | Elevation angle is one of the most significant parameters of land mobile satellite channels, subject to rapid variations in
the case of Low Earth Orbit (LEO) satellite systems. In this paper a novel trace-based framework is proposed and analyzed
which is capable of predicting elevation angle as a function of time during satellite visibility window. Trace-time based
modeling makes the framework practical for real-time evaluation of elevation angle and its alteration incurred by communication
links in LEO satellite systems. The proposed method is particularly suitable for development of communication channel models
and services in mobile LEO satellite networks where path variability is of great importance. |
