The Blue Force Tracker system uses a small transmitter mounted on a vehicle, an aircraft or an individual that sends continuous signals to a Global Positioning System satellite and back to a computer in a secure command post. The command post computer shows precise locations within a 10-foot radius of tracked individuals, vehicles or aircraft on ever-changing map displays.
“This critical technology provides department personnel with the confidence to travel into highly dangerous areas, knowing there is an over-watch and a reaction capability to help them at the push of a button,” according to a State Department fiscal 2012 budget document presented to Congress. About $9.4 million was being sought to support the tracking system in Iraq next year.
