Integrating a Global TT&C Network

Abstract

Global Networks come in a couple of different flavors; dedicated resources with a singular mission or shared ground system resources integrated into cohesive ground network solution. The dedicated network solution provides global coverage to a single mission or constellation, which has many benefits to the owner, however, also incurs substantial cost for implementation, operations, sustainment and other "ownership" issues. Priority access is normally a driving requirement for the development of a dedicated network. Shared Network resources provide an alternative to what could be a very expensive dedicated network solution. Many of the challenges and disadvantages of a dedicated, user-owned network are easily diminished by the utilization of a shared infrastructure. However, this is not to say that the Shared Network solution does not have its own interesting and unique challenges. This paper will discuss the issues and challenges associated with providing global coverage to space-based missions from a global, shared network infrastructure that is managed and measured by its ability to deliver the required services on a very tight budget. © 2012 by Thomas M.
