Application of multistage method of a space object initial orbit determination in the trajectory measuring system

Annotations languages:

A rule, providing the correct use of a multistage method of primary determination of parameters of orbit of space object from data of a few sessions of measuring of co-ordinates of position and radial speed in the conditions when on every session the surplus selection of results of measuring reduce to the estimation of parameters of motion of space object, is offered. It is shown that the errors of method, brought in at the accepted simplifications, do not exceed the size of periodic indignations of parameters, conditioned influencing of eccentric the field of gravitation Earth, that fully possibly at determination of orbit to space object on the initial stage of accompaniment.
