World-wide link availability for geostationary and critically inclined orbits including rain attenuation effects
Abstract
Link availability for constellations of satellites in geostationary and critically inclined orbits is computed using a predictor model based on the Crane 8 region worldwide rain attenuation model. The results are contrasted to percent Earth visibility computations which do not include rain attenuation. For geostationary satellite constellations, the quantitative relationship for Earth coverage vs link margin vs availability vs number of satellites is described by a set of parametric curves.
