Satellite Efficiency regarding SAA

Gives an overview of the time spend in- and outside the SAA given a certain orbit.

Input any Longitude Latitude and Altitude into SAA and it will return 1 for operational and 0 for not operational due to a radiation higher than 0.8 protons/cm^2/s. An edited version of the orbit propagator TwoBody from Satellite Orbits: Models, Methods and Applications (v1.0.0), which now includes J2 pertubation and better performance, is used.
See files for documentation.
True anomaly and excentricity is always assumed to be 0 (If you want to change that go to position_vector.m and change the input arguments and values forwarded to TwoBody).
