MILSATCOM system link availability prediction for polar and inclined orbits
Abstract
A numerical link availability prediction model including the combined effects of rain attenuation, atmospheric absorption, slant range differential, and spacecraft antenna pattern effects, has been formulated and programmed using Crane's (1971) rain rate distribution and climate region definitions. The model computes a distribution and resultant contour levels of link availability within a satellite's field of view for a specified value of link margin. The present paper describes the application of this model to MILSATCOM system link architecture for satellites in polar and inclined orbits; computed results for selected 12 and 24 hour period orbits are presented.
