... Satellite data ] . SMIS ] . The program calculates the satellite orbit using ephemeris data in either predict-telegrams (APT predict, TBUS data) or 2-line NORAD format (TLE data). It determines the start and finish times of acquisition session and stores the data for antenna control during the receipt onto the hard disk. The program creates session schedules, supports selection of specific regions for observation and automatic filtration of satellite passes over the selected regions. ...
