Method for determining orbit position of geosynchronous earth orbit satellite

Abstract

The invention discloses a method for determining orbit position of a geosynchronous earth orbit satellite, which comprises the steps of determining a to-be-selected arc section and frequency resource demand of the satellite; inputting more than one frequency resource demand, and sequentially forming one or more policies according to importance of the frequency resource demand; determining a special orbit position in the to-be-selected arc section, and further determining frequency resource which can be obtained most probably and is related with the orbit position; selecting a plurality of to-be-selected orbit positions based on an orbit position isolation principle according to the present satellite network information and on-orbit satellite information, wherein influence caused by the special orbit position has to be considered; calculating values of all the to-be-selected orbit positions according to determined policies; carrying out quantitative ordering of all the to-be-selected orbit positions by a grey correlation degree method, and selecting the optimal orbit position according to result of the quantitative ordering. The method for determining orbit position of the geosynchronous earth orbit satellite can effectively determine the optimal orbit position of a satellite system under a multi-target condition, thereby realizing maximum compatibility and accomplishing maximum feasibility of coordination of a to-be-declared satellite network and an existing satellite network.

Description

technical field [0001] The invention relates to a method for determining the orbit position (orbit position) of a satellite in geostationary orbit, which is used for satellite orbit design in systems such as communication, navigation, and remote sensing utilizing geostationary orbit satellites, and belongs to the technical field of aerospace radio spectrum. Background technique [0002] Reporting the satellite network to the International Telecommunication Union is the only way for a country to obtain satellite frequency orbit resources under the framework of international regulations. Only when the international coordination of the satellite network is completed, and the frequency assignment is entered into the master list of international frequency registers in accordance with the Radio Regulations and Procedures of the International Telecommunication Union, can satellites be legally launched and the corresponding satellite network put into use. For geostationary satellite...
