Military Space Ground Link Interface Unit

As satellite usage increases, several efforts have been initiated to develop new payload delivery protocols, though existing payload protocols must also continue to be supported. Similarly, the migration of end users to new WAN protocols has resulted in requirements to seamlessly support both existing and new formats. A modular Space Ground Link Interface Unit is needed to provide translation between the various satellite payloads and end user protocols. SRC proposes an innovative, comprehensive, and efficient solution to achieve the goals of the Space Ground Link Interface Unit. By developing a Common Payload Format, SRC will reduce the required number of unique interfaces resulting in simplified development, improved scalability, and reduces cost. Routing and switching between two different protocols is not a straightforward task, however SRC specifies solutions to maintain routing tables and address mapping for various operational requirements. Most importantly, SRC has previously developed a modular architecture, designed expressly to bridge network protocols to wireless channels, that will readily support the Space Ground Link Interface Unit requirements. Using existing IP and ATM modules, SRC will demonstrate the se s the basis for continuing development.
