In 1994, the Defense Airborne Reconnaissance Office established a new standard to ensure interoperability between US imagery intelligence and reconnaissance systems, the Common IMagery Ground/Surface System (CIGSS) standard. The US Marine Corps Tactical Exploitation Group (TEG) is the first imagery reconnaissance system to be designed and built from the beginning to meet the CIGSS standard.
The TEG system is a mobile imagery reconnaissance ground system initially designed to process ATARS, APG-73, and ASARS II imagery. It is currently being produced by GDE Systems Inc., in San Diego, California. Each system consists of a trailer-mounted antenna, three HMMWV-mounted shelters, and a trailered pop-up tent containing the necessary imagery data link, processing, exploitation, and dissemination components. This paper will outline the CIGSS standard, and describe the TEG system architecture and its technical capabilities.
