In this time of declining Department of Defense budgets, it is imperative that more cost effective solutions are identified for meeting present requirements. Lockheed Martin Tactical Communication Systems is under contract to develop a Commercial Off-The-Shelf-based communication ground terminal that is Common Data Link (CDL) compatible. This system is called the Tactical Interoperable Ground Data Link or TIGDL. The TIGDL is made up of more than 50% COTS, and provides the flexibility and scaleability to add and/or delete functions depending on user requirements and constraints. The TIGDL includes an antenna trailer that is capable of being towed by a High Mobility Multi-Wheeled Vehicle. The TIGDL will also provide an Asynchronous Transfer Mode fiber optics interface to the user that meets the Common Image Ground/Surface Station requirements.
