This application discloses an airborne satellite communication system and its satellite link switching method. The modem of the airborne satellite communication system includes a plurality of core protocol boards, a beam configuration information interaction module, and is used to convert the currently used core The protocol board is connected to the switching connection module of the antenna; the method includes: starting the target core protocol board; based on the current core protocol board being used, sending the access time and current location information of the target core protocol board to The network operation center of the current core protocol board; based on the feedback information of the network operation center of the current core protocol board, obtain the beam configuration information of the target core protocol board and write it into the beam configuration information interaction module; switch the target core protocol board Connected to the antenna; the target core protocol board performs communication channel establishment and star tracking based on the read beam configuration information. The application shortens the interruption time of satellite communication during the satellite link switching process.
Description
technical field [0001] The present application relates to the technical field of satellite communication, and in particular, to an airborne satellite communication system and a satellite link switching method thereof. Background technique [0002] In recent years, for airborne satellite communication systems mounted on aircraft, spacecraft, etc., due to the continuous increase in the use of crew communication and in-flight entertainment equipment, their modems have also been derived from the traditional single communication board structure. structure to adapt to the switching between multi-band, high and low orbit satellite systems. However, in the related art, when switching boards are used, the efficiency is often low, so that the interruption time of satellite communication is long. [0003] In view of this, providing a solution to the above-mentioned technical problems is an urgent need for those skilled in the art. SUMMARY OF THE INVENTION [0004] The purpose of th...
