Acoustic transponders allow ships to determine a position relative to a transponder net with an accuracy of 2 to 5 meters. Because they are accurate and economical, compared with more sophisticated systems, they are useful navigation aids in those parts of the world where long range navigation signals are not available and satellite passes are infrequent. This article describes acoustic transponder hardware and deployment, and explains navigation calculations and transponder calibration. The mathematical techniques employed in computer solutions are described.
