The quality of service of mobile satellite reception can be improved by using multi-satellite diversity (angle diversity). The recently finalised MiLADY project targeted therefore on the evaluation and modeling of the multi-satellite propagation channel for land mobile users with focus on broadcasting applications. The narrowband model combines the parameters from two measurement campaigns: in the U.S. the power levels of the Satellite Digital Audio Radio Services was recorded with a high sample rate to analyze fast and slow fading effects in great detail. In a complementary campaign signals of Global Navigation Satellite Systems (GNSS) were analyzed to obtain information about the slow fading correlation for almost any satellite constellation.
