cosmonautics; processing trajectory measurements for accurate determination of parameters of spacecraft near-circular orbit. SUBSTANCE: according to invention, method includes four stages of processing trajectory data. After first stage, data pertaining to orientation of plane of orbit are stored and are filtered together with similar data stored during several days. Accurate parameters of plane of orbit are used at the following stage where estimations of four parameters of motion in plane of orbit are obtained. These estimations are stored and filtered together with similar data stored during several days and accurate magnitudes of parameters of motion in plane of orbit are obtained. In processing the data, agreement criterion χ2 (chi square) is used. EFFECT: storage of data with ageing taken into account for reliable determination of orbit parameters at reduced number of communication sessions. 1 dwg
