Less Faulty and Simpler Statistical Prediction of Sun-Synchronous Polar LEO Satellite Visions for Ground Stations

Remote sensing satellites can send almost complete images of whole earth surface in period of few days, if they are launched in sun-synchronous polar low orbits. The volume of daily received information can affect the predetermination of station location and the design of data archiving devices; that´s why this paper has focused on daily satellite visions by each station. The number of satellite daily passes over each ground station and the duration of these passes depend on the station position and satellite altitude. Although exact analytical relations have been introduced for predicting visions´ number and duration in literature, but they are too complicated; some simplified equations have also been introduced but some significant errors appears in results; these errors have been revealed and compared with the results of simpler statistical equations, in this paper in comparison with real statistical data.
