Abstract
The method for identification of a set of satellites, arranged on GEO orbit, consists of receiving satellite signals; determining antenna beams strength; detecting beams that are local maximums according to the antenna structure, defined by the number of beams and their coordinates in the antenna plane; and approximating the GEO orbit using the strength of the received signals, wherein the satellites' identification is carried out through the local maximums situated on or in a defined range of the approximated GEO curve, according to the information for the geographic position of each satellite and the antenna orientation. Projection probability coefficients of a given satellite in a given area of the antenna plane are used for satellites' identifications. The information about the geographic position of each satellite may be corrected by azimuth, elevation and roll angles, according to the inaccuracy of the antenna installation. It is possible after detection of the strength of each beam to introduce a correction, reflecting the signal-to-noise ratio. In this case, it is expedient to amplify the signals corresponding to the received signals' strengths by the square or bi-square law.
