Use of gps for determining motion parameters of space station mir

摘要

results of processing GPS measurements obtained on Space Station Mir are presented and processing technique is described.Processing is performed in two steps.First,the interval being processed is divided into short(a few minutes in length) subintervals and measurements on every subinterval are approximated by normal points.Igeneratingthe normal points the station motion is considered as Keplerian.Then,using the obtained normal points,Mminimization of the functional on solutions of rather detailed equations of the station motion gives an approximation of its actual motion.This approximation is used to provide the navigational reference for results of researches performed on the station and can be used in coping with the flight control prob lems.
