The increasing use of space stations in circular low-orbit in the space research service (and other services) necessitates the development of dynamic sharing models in which the potential interference from the space station can be treated as a time-varying function. This Report defines analytical tools for calculating visibility statistics for low-orbiting spacecraft in circular orbits (see Note 1) as seen from a specific point on the Earth’s surface.
