Abstract:

A submariner is able to estimate the course of a ship from his record of successive bearings on the ship. The bearings only technique provides a mathematical approximation which uses this data to estimate the angle to bow of the ship. This study shows that the accuracy of the bearings only estimate of the angle to bow increases with increasing values of the ratio speed of shipspeed of submarine. Author
