Method and system for carrying out data transmission through utilization of antennas of invalid satellite

Abstract

The invention discloses a method and system for carrying out data transmission through utilization of antennas of an invalid satellite. The method comprises the steps that 1, an on-orbit service platform carrying an on-orbit service module is transmitted, after the on-orbit service platform enters an orbit, the on-orbit service platform approaches to the invalid satellite and is aligned with the invalid satellite, the on-orbit service module and the invalid satellite are physically connected, a combined unit is despun, the on-orbit service platform is separated, a solar cell panel is unfolded,and a tail end paw is stretched, so transmission signal feeder lines and satellite antennas are physically connected; 2, the on-orbit service module carries an electronic music transmitter, a GPS / Beidou navigation positioning receiver and a Beidou signal repeater, and a Dongfanghong music signal, navigation system time and a short message are transmitted through the antennas of the invalid satellite; and 3, a ground user receives the music signal, a transmission standard time signal and the short message and finishes listening to the music, calibrating the time and checking the message, and the signal is received and broadcasted through a base station in a region in which the signal coverage is weak, so the ground user employs the signal.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a data transmission method and system using a failed satellite antenna. Background technique [0002] With the continuous development of the space industry, human beings continue to explore, develop and utilize outer space. The number of satellites flying in orbit is increasing. However, due to fuel exhaustion, attitude / orbit control system failure, etc., some or even all functions of satellites may fail, resulting in the formation of large-scale space junk. Some of the invalid satellites will be moved to the "grave orbit" 200-300km higher than the geostationary orbit according to the recommendation of the Inter-Agency Space Debris Coordination Committee (IADC) after the end of their working life. However, there are many usable and valuable parts on the satellites in the "grave orbit". According to a rough estimate, there are currently hundreds of decommissioned satellites in...
