Influence of driving direction on Land Mobile Satellite channels

State-of-the-art statistical Land Mobile Satellite (LMS) channel models which predict the availability of satellite systems do not include the driving direction as a model parameter. In this contribution we show that the driving direction has indeed a significant impact on the availability of single and multi-satellite systems and should therefore be further investigated. The extensive data set on which the proposed study is based has been obtained via an image-based approach applied on the output of a hemispheric camera mounted on a vehicle
