Background
With the continuous exploration of human beings in the space field, satellite communication technology is vigorously developed, the types and data volumes of satellite load data are increased, and higher requirements are also put forward on a satellite downlink data processing end. In the satellite on-orbit operation stage, the original data is converted into binary data stream through operations such as compression, encryption, scrambling and the like, then the binary data stream is downloaded to the ground through steps such as packaging, satellite-ground link transmission, ground station receiving and the like, and finally, the binary data stream is restored into real data collected by satellite loads through steps such as station transmission, data descrambling, decryption, decompression and the like.
In order to download the load original data to the ground, the satellite needs to establish a satellite-ground transmission link with each ground station, so that reliable transmission of the data is ensured. Low orbit satellites have limited ground station visibility and satellite-to-ground data link transmission times due to limited orbital altitude and other conditions.
