METHOD FOR CONTROLLING A GROUND-BASED ANTENNA COMPLEX TO ENSURE RECEPTION AND TRANSMISSION OF INFORMATION IN THE COMMUNICATION PATH WITH A SPACE VEHICLE IN A QUASI-GEOSTATIONARY ORBIT AND CONTROL SYSTEM FOR IMPLEMENTATION THEREOF

摘要

FIELD: controlling.;SUBSTANCE: group of inventions relates to control of a ground-based antenna complex (GAC) with a limited directional pattern relative to the angular oscillation amplitudes of the subsatellite point of a space vehicle (SV) in a quasi-geostationary orbit (QGSO). According to the method, a daily trajectory of the subsatellite point of the SV is approximated by a Lissajous figure, based whereon, the geometric centre of the SV is calculated. The stability of the SV information reception and transmission path is ensured by the condition of finding the actual angle between the vector of the current position of the SV relative to the GAC and the vector of the geometric centre of the SV within the directional pattern of the GAC. The proposed control system determines, in particular, the accuracy of the applied analytical method within the interval of prediction of the SV movement.;EFFECT: possibility of controlling the GAC receiving information from the SV in the QGSO based on the analytical method for predicting the orbit of said SV based on the calculated coordinates of the subsatellite point thereof.;2 cl, 1 dwg
