Claim 15:
16. A method for coordination of a plurality of munitions in a salvo to form a constellation of munitions in a Global Positioning System (GPS) denied attack of a plurality of ground targets wherein each munition is provided with a datalink communication system to communicate with other munitions and a navigation system for guiding the munition in flight, the method comprising:
determining a relative position of each munition relative to the other munitions in the salvo via each munitions' datalink communication system wherein Two-Way Timing and Ranging (TRTW) techniques are utilized by the navigation system of each munition to determine positioning of each munition relative to one another;
determining a distance range of each munition relative to the other munitions in the salvo via each munitions' datalink communication system;
determining a constellation formation of the plurality of munitions in the salvo based upon the determined relative position and distance range of each munition relative to one another;
determining a target seeker basket coordinate respectively for each munition determined to be in the constellation formation relative to the plurality of ground targets; and
navigating each munition in the constellation formation to its respective target seeker basket coordinate via the navigation system of each munition, wherein navigating each munition to its respective target seeker basket coordinate includes coordinating a flight path of each munition in the salvo relative to one another regarding the flight path of each munition to its respective determined target seeker basket, and wherein coordinating a flight path of each munition includes determining an Estimated Time of Arrival (ETA) for each munition relative to its determined target seeker basket whereby a change in navigation for each munition is caused when necessary such that each munition arrives at its determined seeker basket at an approximate same time.
