Abstract

A situation awareness display device for providing a graphical display of e relative position of remote units moving along with and in proximity to the local unit utilizing the device. The device is comprised of a tracking means for determining the instantaneous position of the local unit, a communications means for communicating that local position information to cooperating remote units over an external communication link, and receiving the position information of those remote unit over that same external link, a navigation means for deriving course following information, direction and velocity of said display device from said local unit position information, a main processing means for controlling the flow of information within said device and for deriving the relative position of the remote units with respect to the local unit from their respective position information, and a display means for retrieving and graphically displaying said stored relative position information in a uniquely configured display format showing the relative positions of the remote units from the perspective of the local unit.

Dependent claims

A situation awareness display device, comprising:

tracking means for determining instantaneous position information of a local unit utilizing said display device, said position information repeatedly updated at preprogrammed time intervals;
navigation means for deriving direction and velocity of said device from said local unit position information of said tracking means, said navigation means computing progress toward a series of programmed waypoints;
programmable communication means for transmitting said local unit position information over an external radio to remote units having their own local situation awareness display device, said programmable communication means receiving the position information of said remote units over said external radio;
processing means for controlling the flow of information within said device, said processing means deriving the relative position of said remote units with respect to said local unit from said position information, and said processing means storing said relative position information for retrieval;
display means for retrieving and graphically displaying said stored relative position information, said graphical display showing the relative position of remote units in relation to and from the perspective of said local unit;
and
control means for providing operator control over said display device.
