% Compute the eclipse duration in earth orbit. Uses the orbit radius at perigee for the computation. The orbital elements are: [Semi-major axis, Inclination, Right ascension of the ascending node, Argument of perigee, Eccentricity, Mean Anomaly] Type EarthEclipseDuration for a demo in a 7000 km 85 deg orbit. Uses SunBeta and EclipseDuration. -------------------------------------------------------------------------- Form: [d, dMax] = EarthEclipseDuration( el, jD ) -------------------------------------------------------------------------- ------ Inputs ------ el (1,6) [a i W w e M] jD (1,:) Julian date (days) ------- Outputs ------- d (1,:) Eclipse duration (sec) dMax (1,1) Maximum eclipse duration (sec) --------------------------------------------------------------------------
