An Analytical Method for Satellite Orbit Forecasting

The orbit forecasting plays an important role in the observing and tracking of plentiful space objects. The analytical method is always used due to the large amount of the objects and not very high accuracy of forecasting. A method based on the position and velocity derived from the mean orbit elements directly is given, which is to avoid the problem of singularity in calculating the periodic terms of orbit elements variation, thus the process and software can be simplified.
