After it became more heavily used, it was determined that the Army needed its own secure hub on a military base in Germany. This hub was located in [[Mannheim, Germany]] outside of Coleman Barracks at a ___location known as the "tank-farm". This ___location was chosen because it already housed other satellite hubs, one of which was for AFN.
The Land Earth Station (LES) portion of the system was maintained by a company called Data Path (which was acquired by Rockwell Collins in 2009<ref>http://www.rockwellcollins.com/news/page12220.html</ref>). The servers that processed the messages and GPS ___location information through the QTRACS software were initially housed in Friedrichsfeld, [[Germany]] and maintained by the United States Army in Europe (USAREUR) G4 office. The G4 contracted this work out to the Titan Corporation (now owned by L3 Communications) and was later picked up by PEO EIS<ref>http://www.eis.army.mil/</ref>. The servers were later moved to [[Kilbourne Kasserne]] in [[Schwetzingen]]. This move was made because the facility at Friedrichsfeld was not robust enough and had a poor communications paths with no redundancy. The site in Schwetzingen, also known as "Site-S", had better comms and was also an official military [[Network Operations Center]] (NOC).
At its height, there were three server stacks for processing DTRACS data. One stack for European devices, another for devices in SWA and a third for receiving a split-feed from the KBR (Kellog Brown and Root) owned and operated server. While KBR had their own vehicles and server, all three systems used the same satellite for their communications. As of January 2010 the KBR solution still exists, but was moved to Ramstein Airbase.
