% Solar flux and direction from the sun with seasonal variation. Uses SunV1 to locate the sun in the Eart-centered inertial (ECI) frame. The nominal solar flux at 1 AU is 1367 W/m2. The same scaling law is used by SolarFluxDemo, which also returns the sun unit vector in the Earth-centered (ECI) frame, but using the PlanetPosition to compute the sun vector instead of Almanac function SunV1. The results are therefore slightly different. -------------------------------------------------------------------------- Form: [flux,u] = TerrestrialSolarFlux( jD ) -------------------------------------------------------------------------- ------ Inputs ------ jD (1,:) Julian Date ------- Outputs ------- flux (1,:) Solar flux (watts/m^2) u (3,:) Sun unit vector --------------------------------------------------------------------------
