Satellite communication method and device based on semantic compression and storage medium

The invention provides a satellite communication method and device based on semantic compression and a storage medium, and the method comprises the steps: carrying out the information source-channel joint coding of target data through a current satellite, obtaining a semantic information bit, and carrying out the lossy compression of the semantic information bit; sorting the semantic information bits according to the priority of the semantic information bits to obtain a semantic information bit stream; establishing a corresponding position relationship between the semantic information bit stream and semantic information bits to obtain index position information; under the condition of establishing a communication link with the target ground equipment, sending the semantic information bit stream and the index position information to the target ground equipment; under the condition that the communication link is interrupted, determining a target satellite in the remaining satellites in the satellite cluster; se
