ESTIMATES OF THE ACCURACY OF CONTROL OF THE ORBIT OF METEOR-3 SATELLITES USING A SYSTEM TO PREDICT THE SATELLITE MOVEMENT, AS PART OF THE RADIATION BUDGET PROJECT

A system to predict the movement of Meteor satellites is considered. A n analytical model of the movement is constructed based on perturbatio n theory with a zero approximation in the form of an intermediate orbi t which is the solution of a generalised problem for two fixed centres . A procedure of differential refinement of the orbital elements using previous measurements is used to decrease the prediction error.
