High Quality Content by WIKIPEDIA articles! Blue Force Tracking is a United States military term used to denote a GPS-enabled system that provides military commanders and forces with location information about friendly military forces. In military symbology, the color blue is typically used to designate friendly forces while red is used for enemies, and green or yellow are used for neutral forces. Blue Force Tracking systems consist of a computer, used to display location information, a satellite terminal and satellite antenna, used to transmit location and other military data, a Global Positioning System receiver, command-and-control software, and mapping software, usually in the form of a GIS, that plots the BFT device on a map. The system displays the location of the host vehicle on the computer's terrain-map display, along with the locations of other platforms in their respective locations. BFT can also be used to send and receive text and imagery messages, and Blue Force Tracking has a mechanism for reporting the locations of enemy forces and other battlefield conditions.
