Mobile satellite channel with angle diversity: The MiLADY project

Future broadcasting to mobile services may consider satellite angle diversity to overcome fading propagation effects on the land mobile satellite (LMS) environment. For that reason, an experimental campaign for gathering relevant experimental data and improve angle diversity models has been carried out in the MILADY project. Its main focus is on the analysis of multi-satellite systems and the consolidation of narrowband channel models. The availability of existing satellite constellations permitted performing on-field propagation experiments. Two major measurement campaigns were carried out, one in the US using the S-DARS satellites from XM Sirius satellites and another one in Europe using GPS satellites. Results on data analysis and a preliminary model development have been performed.
