Remote Satellites Computing transmission and Key Technologies

Abstract

The diversity of remote sensing data and the increase of acquisition ability make the amount of data generated on the satellite increase geometrically.This situation puts tremendous pressure on the remote satellite data transmission system.This makes the remote satellite data transmission system unable to meet the needs of real-time transmission and becomes the bottleneck of remote sensing data application.The research on massive remote satellite data transmission systems and technology is one of the frontier fi elds of international satellite information network science and technology.Focused on the critical problems of remote satellite real-time data transmission bottleneck, remote sensing data transmission timeliness, remote sensing load utilization, and onboard storage, combined with the traditional satellite data transmission system with onboard intelligent processing, a new remote satellite computing transmission framework was proposed, and its key technologies were analyzed.
