The Blue Force Tracker System

Blue Force Tracker is a system that gives commanders and troops in the field a real-time picture of the battlefield not possible with conventional maps. This improves situational awareness and reduces the possibility of friendly fire. It also allows headquarters to issue orders much more efficiently than by previous forms of radio communication. GPS positioning provides the main data source for Blue Force Tracking. Unit locations and movements, along with intelligence data on enemy forces and battlefield conditions, are distributed over a satellite communications network that the Army calls FBCB2.
