Abstract

Abstract

With the rapid development of aerospace electronic technology, especially the wide use of Commercial Off-The-Shelf(COTS), the space computing capacity has increased significantly. Space edge computing organizes the widely dispersed space-based computing resources into a distributed and collaborative cloud environment through inter-satellite links, so as to realize resource complementarity and task collaboration, which can effectively get rid of the dependence on the ground and improve the speed of service response. Firstly, the requirements development status, existing problems and challenges of space edge computing are clarified. Then, a space edge computing architecture is proposed, which is described from the perspectives of physical architecture, functional architecture, software architecture and service process. Finally, the key technologies are summarized and analyzed in order to provide valuable suggestions and references for follow-up research.
