CENTERBOARD is the central processor computers for the DOD World Wide High Frequency Direction Finding System. HF-DF stations detect radio signals from aircraft or ships, and calculate the direction, or line of bearing, of the radio transmitter from the direction finding antenna. When the same signal is received by two or more antennae, the intersection of the lines of bearing mark the transmitter's location
