Modeling of terrains for simulation of integrated mobile terrestrial and satellite communications systems

In this paper we present methods to generate models of mountainous regions. For these regions statistical methods are unsuitable to predict the service coverage, blocking and termination probabilities for systems involving fast moving satellites. We present methods using modeled terrains to analyze the service coverage in satellite integrated mobile communications systems. Results of service coverage analyses based on these methods are presented for proposed non-geostationary satellite systems
