Scientists are greatly interested in images sent from remote sensing satellites which are usually launched in sun-synchronous polar low orbits. Each satellite has definite number of daily passes over each ground station; the number of passes and the duration of them depend on the station location and satellite altitude. As the number of passes or the time duration of them increases, the complexity of data archiving devices in the station will also increase. This paper introduces mathematical equations which show the relationship between satellite passes, station's geographical position and satellite altitude.
