ESTIMATION SYSTEM OF ACCURACY OF DETERMINING ARTIFICIAL EARTH SATELLITE MOVEMENT PARAMETRES Russian patent published in 2010 - IPC B64G3/00 G09B23/00 

FIELD: measurement equipment.

SUBSTANCE: invention refers to equipment for forming trajectory measurements, determining movement parametres of artificial earth satellite (AES) according to these measurements and for estimation of accuracy of that determination at measuring interval. Invention can be used in ground and airborne control complexes of AES movement, as well as at schematic design stage. System includes basic data unit, AES movement parametre predicting unit, calculation unit of values of the measured parametre, unit for determining AES movement parametres, trajectory measurement modelling unit, unit for estimation of accuracy of determining AES movement parametres. Output of the latter is output of estimation system. The units being used and their connections allow increasing the number of pre-set parametres required for estimation and increase of the number of realisations of modelled trajectory measurements. This provides improvement of accuracy and reliability of estimation of the procedure for determining AES movement parametres.

EFFECT: providing estimations of accuracy of determining orbit parametres for AES of any class (low-orbit, middle-orbit and high-orbit AES), estimation of accuracy of AES correction and manoeuvre, as well as control of accuracy of determining parametres of orbits of operated EAS.
