The invention discloses an airborne satellite communication system and a satellite link switching method thereof. A modem of the airborne satellite communication system comprises a plurality of core protocol board cards, a beam configuration information interaction module, and a switching connection module used for connecting the currently used core protocol board card to an antenna; the method comprises the following steps: starting up a target core protocol board card; sending the access moment and the current position information of the target core protocol board card to a network operation center of the current core protocol board card based on the current core protocol board card which is being used; obtaining beam configuration information of a target core protocol board card based on feedback information of a network operation center of the current core protocol board card, and writing the beam configuration information into a beam configuration information interaction module; switching the target core protocol board card to be connected to the antenna; and the target core protocol board card performs communication channel establishment and satellite tracking according to the read beam configuration information. According to the invention, the interruption duration of satellite communication in the satellite link switching process is shortened.
Description
Technical field [0001] The present application relates to the field of satellite communication, and in particular, there is an airborne / satellite system and its satellite link switching method. Background technique [0002] In recent years, for the airborne satellite communication system equipped with aircraft, spacecraft, etc., due to the continuous improvement of the needs of the unit communication and machine entertainment equipment, its modem is also derived from the traditional single-pass card structure. Structure to accommodate switch between multi-band, high-low rail satellite systems. However, in the related art, when the switchboard card is used, it is often less efficient, so that the interruption of satellite communication is longer. [0003] In view of this, it is provided to solve the above technical problems, which is already urgent to pay attention to those skilled in the art. Inventive content [0004] The purpose of this application is to provide an airborne ...
