The goal of our work is to lower financial and engineering barriers that hinder access to science data and telemetry generated by satellites and other space systems. We are developing ground infrastructure to increase network access to space-borne assets. We are making this infrastructure robust and reliable while being built from lower cost, commodity components. Our vision for this network infrastructure is a loose federation of ground stations that provides global, cross-mission support. This federated ground station network (FGN) will harness the strengths and diversity in global ground stations that are under different administrative domains to increase network connectivity to satellites and to enhance basic ground station capabilities. We are developing infrastructure for the virtualization of ground stations. The decomposition of ground stations into core components enables dynamic composition of virtual ground stations across multiple independent installations. We are developing recovery-oriented computing techniques to build highly available systems from less reliable commodity components. These techniques assume failures are inevitable and focus on rapid failure detection and recovery. We are also developing autonomous, network-centric ground station installations. Capabilities of these installations include: performing automated satellite passes; stitching satellite data products from multiple installation sources; interfacing with human and software agent control; running local missionspecific software; and coordinating with other installations to optimize communication opportunities. This paper provides an overview of related research and describes our concept of operations for an FGN.

“…As NASA and other space agencies operate a greater number of smaller spacecraft including missions with spacecraft in formation, these missions require affordable and flexible communication capabilities. The Space Network's DAS is strategically positioned to be an efficient service provider to this class of customers and to emerging space internetworking concepts [5,6,7]. The modular DAS architecture provides a low-data rate, low-cost service that can be easily expanded to a nearly limitless number of users.…”

The Demand Access System (DAS) of the NASA Space Network offers a new and innovative service for space operations by providing continuous and automated communication links via the Tracking and Data Relay Satellite System (TDRSS). Operational in October 2002, the Demand Access System expands the TDRSS Multiple Access return (spacecraft-to-ground) capabilities by building on the availability of ground-based Commercial Off-the-Shelf (COTS) systems, such as the Third Generation Multiple Access Beamformer Subsystem (TGBFS) and the Programmable Telemetry Processor (PTP), and by using networking standards, including TCP/IP and web-based interfaces. This paper reviews the DAS architecture, noting the use of COTS hardware components, as well as its automated approach to space operations for Earth-science and space science missions.

Context-awareness is inherent in anticipated interplanetary missions. Swarm technologies [11]use context-awareness in short-haul networks between components, and long-distance networks allow communication with Earth. However, the propagation delays limit real-time communications, deep space being an environment in which the speed of light becomes a restriction. Therefore, the development of a protocol stack which is adaptive to application requirements and external influences will help to maximise communication synchronicity.As part of a first year doctorate research programme, this paper correlates current stack functionalities with interplanetary application requirements. A redesigned stack proposes to resolve this misalignment. Context-awareness is incorporated, enabling intelligent protocol selection using application layer knowledge and environmental information, with particular attention given to transport protocols. The paper concludes by considering transport protocol characteristics when deployed beside a context-aware layer, with the longterm aim being the development of a transport protocol suitable for deployment in the state-of-theart context-aware stack.
