% Computes the normalized sun intensity for an earth geosynchronous orbit.
--------------------------------------------------------------------------
Form:
[n, eclipseType] = GeoEclps( alpha, beta, dEarth )
--------------------------------------------------------------------------
------
Inputs
------
alpha (1,1) Angle in the orbit plane between the sun and
the spacecraft ( 0 to 2 pi radians )
beta (1,1) Angle between the sun vector and the orbit
plane ( -0.409 < beta < 0.409 radians for
zero inclination )
dEarth (1,1) Distance to the earth. If not entered assumes 42167 km
-------
Outputs
-------
n (1,1) Normalized sun intensity ( 0 ? n ? 1 )
eclipseType (1,1) 0 = none, 1 = partial, 2 = annular, 3 = total
