Low Earth Orbit Coverage Analysis Tool (LEOCAT) v0.1

This python package is made to efficiently compute satellite regional access (the portion of Earth observed) for conical and rectangular fields of view (FOVs), utilizing efficient algorithms, as well as numpy vectorization and jit compilation via numba.

Access calculations are split into two major categories: time-series and grid-point series (or GP series). In time-series approaches, the satellite is propagated forward one step at a time, and access is computed. In GP series approaches, the time at which the satellite observes a point on Earth (a GP) is input, and the output is a time-series. The former is for accurate FOV area coverage over short spans (e.g., a day of simulation) while the latter is for coverage over months or years, which reveals satellite observation capability in the long term.
