ON THE ACCURACY OF THE ORBITAL ELEMENTS OF ARTIFICIAL EARTH SATELLITES (O Tochnosti Elementov Orbit Iskusstvennykh Sputnikov Zemli),

Abstract

The criterion for choosing intervals of time has been obtained when the improvement of orbit elements of artificial earth satellites is performed by the least squares method. The time interval is to be chosen in such a way that the residuals of the equations of observation should be bias-free. The formulae for computing the weight coefficients of the corrections to elements have been also derived. On the basis of these formulae, the criterion has been established permitting to exclude the elements with large errors from the refinement process. An example of the criteria mentioned above has been given in this work. (Author)
