Method for achieving all-weather communication by means of two IGSO communication satellites

Abstract

The invention discloses a method for achieving all-weather communication by means of two inclined geosynchronous satellite orbit (IGSO) communication satellites. The method for achieving all-weather communication by means of the two IGSO communication satellites comprises the steps that the two IGSO communication satellites are placed at co-location positions of one or two geostationary earth orbit (GEO) communication satellites, and the ascensional difference of an ascending node between the two IGSO communication satellites meets the requirement that the two IGSO communications satellite can not be located within the range three degrees above or below the equatorial plane at the same time; when the IGSO communication satellites are located beyond the range three degrees above or below the equatorial plane, a satellite communication ground station conducts the communication application through transparent repeaters or processing repeaters on the IGSO communication satellites; when one IGSO communication satellite is located within the range three degrees above or below the equatorial plane, the satellite communication ground station switches the communication service from the IGSO communication satellite located within the range three degrees above or below the equatorial plane to the other IGSO communication satellite, the communication application is conducted through the transparent repeater or processing repeater on the other IGSO communication satellite, and thus all-weather satellite communication is achieved by the satellite communication ground station through the two IGSO communication satellites.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and in particular relates to a method for realizing all-time communication by utilizing two communication satellites in an inclined geosynchronous orbit (IGSO). Background technique [0002] Satellite frequency orbit refers to the frequency used by satellite stations and the space orbit position of satellites. It is a natural resource that has been developed and utilized by humans with the invention of satellite technology. It is the premise and foundation for the establishment of all satellite systems. With the development of space technology and the massive increase of satellite applications, satellite frequency resources are becoming increasingly tight. Due to the limitation of the antenna receiving capacity, the geostationary orbit (GEO) communication satellites with the same frequency band, the same coverage area or partially overlapped can only be separated by a certain dist...
