Space Data Routers for the Exploitation of Space Data
Martin Goetzelmann · SpaceOps 2012 Conference · 2012
The goal of the “Space-Data Routers ” (SDR) project is to explore concepts for an enhanced architecture for the exploitation of space data capable of mitigating current availability limitations with respect to volume, timeliness, and continuity. The objective is to establish a mission / application-oriented communication overlay for data dissemination on Earth and to include into this overlay space born sources and network nodes. Technically, that is achieved by deploying the Delay Tolerant Networking (DTN) stack and integrating the interfaces of various Space and Internet communication and networking protocols, including TM/TC, Space Packets, and AOS along with Ethernet, TCP/IP and UDP. In addition, the overlay supports and enforces policies for resource and data sharing as well as for data dissemination. These concepts will be implemented through the development of the Space-Data Router, a DTN-enabled device that will interconnect space data providers, ground stations, research centers, and academic institutions in a much more efficient and decentralized manner than today. I. Overview Space data exploitation by research centers and academic institutes today is constrained by limitation in the
