A Forecast Model of Covering Time For Satellites

  Accurate prediction of satellite's covering information is an important application in the military and civil field, it calculates the sub-satellite point track using the orbit parameters and deduces ECEF coordinate of satellite by means of combination of elevation and azimuth, establishing a simple model through the calibration of partial sub-satellite point track, using MATLAB programming to predict the future period of satellite covering time and draw the sub-satellite point track and calculate the elevation／azimuth of satellite's covering period. The model is simple and effective, using the Matlab only instead of professional satellite prediction software.
