Abstract
An electronic system using RF Transmitters, Receivers, Transponders and a Computer are used to measure location and distance. Using a unique method, this system measures the delay between direct and echoed RF signals from different aspects to convert RF propagation delay into triangulated distance information. It is configured to act as a measuring tool for the linesman in the game of football. It is used to spot the ball (determine location), determine if a first down has been achieved (measure/calculate change in location) and aid the linesman in centering the ball on the playfield and assess penalties(give a constant location reading). Unlike radio direction finding methods of locating a football, it has no moving parts and is completely cordless.
