Abstract

A method, apparatus and system are provided to permit an aerial asset to determine its current location and to, in turn, locate and track a target even as efforts are made by others to jam or otherwise hinder offboard communications that may prevent reliance upon GPS or other positioning systems. A method includes receiving, at a navigation control vehicle, information regarding the relative position of a target with respect to each of the at least two sonobuoys. The method also determines a relative position of the target with respect to the navigation control vehicle at least partially based on the information regarding the relative position of the target with respect to each of the at least two sonobuoys. The method provides information regarding the relative position of the target to an aerial asset to facilitate location of the target by the aerial asset.

First claim

That which is claimed:

1. A method comprising:
receiving, at a receiver of a navigation control vehicle, information regarding a relative position of a target with respect to each of at least two sonobuoys;
determining, with a processor, the relative position of the target with respect to the navigation control vehicle at least partially based on the information regarding the relative position of the target with respect to each of the at least two sonobuoys; and
providing info…
