Models of satellites motion

Forecasting of Earth satellite motion is widely used in determining the orbits from measurements, as well as in solving various application tasks: ephemeris calculation for observation means, planning operation of spacecraft hardware, determination of hazardous encounters and reentry time of satellites, etc. Hundreds of thousands of motion forecasts are run annually all over the world. Not only professionals, but also amateurs are involved in this work. 

This section presents the list of services on prediction of satellite motion and on supporting calculations on the basis of using the initial data in the TLE form and on applying enhancements designed for improving the accuracy of prediction. They are intended both for professionals, and for students, post-graduate students and amateurs.
