Abstract
A system, method, and computer readable medium having a tracked package with a source emitting signals through an underwater environment that are detected by a receiver on a tracker and thereby producing a received signal, the tracker also having a controller and a position mechanism. The controller is configured to produce a sample from the received signal, receive velocity data from the position mechanism, and determine an angle relative to the source by comparing the received signal's frequency from a known source frequency and the velocity data.
