Currently in production and fielded with Shadow TUAVsystems, One System GCS has been in Army service since 2001, logging more than 50,000 hours of operation. The US Army is planning to transition all UAV ground control systems system to the One-System’s standard. The system was used to control the Warrior UAV during the ER/MP systems capabilities demonstration in early 2005 and will control the Warrior ER/MP UAVs as they become operational in 2009. The system has also demonstrated control of a U.S. Army Hunter system, and a STANAG 4586 compliant version is scheduled to fly the U.S. Marine Corps Pioneer tactical UAV system in the first quarter of 2006. STANAG 4586 is a NATO standardization agreement that enables various UAVs to share information through common ground stations, thus enhancing interoperability among allied military forces. Future versions of One System GCS will be compatible with this standard. One System(TM) remote video terminal (OSRVT), an addition to the One System GCS is currently in development. The new mobile, manpack- sized unit is capable of receiving, integrating and displaying live video and telemetry data from an array of unmanned aerial vehicles and manned platforms. Soldiers will simultaneously receive live video and geo-location data in separate windows on their small, lightweight video OSRVT terminals. A video “footprint” and icons identifying aggressor units, vehicles, facilities, or natural landscape features will be overlaid on a map in the geo-location window, enabling swift target identification, decision making, and response.
