| - | Previous derivations on this topic were made in years passed to enable calculations with limited numbers of hydrophone channels. This page provides a generalized algorithm for locating a pinger in 3D in a robust, linear manner with an arbitrary number of arbitrarily placed hydrophones. This solution is an unambiguous, precise result that evaluates at all distances and does not require require that the signal originate in the far-field. | + | Previous derivations on this topic were made in years passed to enable calculations with limited numbers of hydrophone channels.

| This method of calculation requires 5 or more hydrophones. Substituting a depth sensor for one of the required hydrophones is possible, and covered below. The submarine does //not// need to be held level to make use of the depth sensor. | This method of calculation requires 5 or more hydrophones.
