Analytic Model for Low Earth Orbit Satellite Solar Power
IEEE Transactions on Aerospace and Electronic Systems, 2020 An analytic model for calculating the instantaneous and average orbital power available to a satellite in a circular low Earth orbit is presented. By accounting for the effects of angle of solar incidence and eclipsing, for both stabilized and tumbling satellites, this model allows for fast, simple, accurate calculations of available power without the ...
