Abstract: A method and system for coordination of a plurality of munitions in a Global Positioning System (GPS) denied attack of a plurality of ground targets. A relative position of each munition is determined relative to the other munitions in the salvo and a distance range is determined of each munition relative to the other munitions in the salvo. A constellation formation is determined for the plurality of munitions in the salvo relative to a target seeker basket such that each munition in the constellation formation is navigated to its respective 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.

Abstract: A method and system for constraining navigational drift in a munition caused by Inertial Measurement Unit (IMU) bias error during flight of the munition in a constellation of a plurality of munitions in a Global Positioning System (GPS) denied attack. Each munition is provided with a datalink communication system to communicate with other munitions in the constellation and a navigation system having an IMU for guiding the munition in flight. An estimated position and covariance of the estimated position is determined for each munition via each munitions’ navigation system. A range of each munition relative to at least one other munition in the munition constellation is determined via each munitions’ datalink communication system. The estimated position and range to at least one other munition in the munition constellation is shared by each munition via each munitions’ datalink communication system. Navigational drift for each munition is determined utilizing the estimated position of at least one other munition and the range to that at least one other munition in the munition constellation. And navigational drift in each munition is constrained by compensating for IMU bias error in each munition utilizing the determined navigational drift for each respective munition in the munition constellation.

Abstract: A method for collaboration of a plurality of nodes includes determining at each node SLAM data for the node, the SLAM data including estimated position of features and/or targets observed and processed by the node using SLAM algorithms and covariance associated with the estimated positions, communicating at each node the node's SLAM data to the other nodes via each nodes' datalink communication system, receiving at each node SLAM data communicated from the other nodes via each node's datalink communication system, combining at each node the node's SLAM data and the SLAM data received from the other nodes based on features or targets included in SLAM data from the other nodes, refining at each node estimated positions of features and/or targets based on results of the combining, and navigating each node to a target at the target destination as a function of at least one of the refined estimated positions.

Abstract: A method and system for coordinating munitions in a salvo to form a constellation in a Global Positioning System (GPS) denied attack of a plurality of targets. Each munition is provided with a datalink communication system to communicate with other munitions and a navigation system for guiding the munition in flight. An estimated position of each munition is determined relative to the other munitions in the salvo via each munitions' datalink communication system. Two-Way Timing and Ranging (TRTW) techniques are utilized to determine positioning of each munition relative to one another. A distance range of each munition relative to the other munitions in the salvo is determined via each munitions' datalink communication system. A constellation formation of the plurality of munitions in the salvo is determined based upon the determined relative position and distance range of each munition relative to one another. A target seeker basket coordinate respectively for each munition in the constellation formation is determined relative to an array of targets. Each munition in the constellation is then navigated in flight to its respective target seeker basket coordinate via its navigation system, wherein navigating to a respective target seeker basket includes coordinating a flight path of each munition in the constellation relative to one another to its respective determined target seeker basket. And coordinating the flight path of each munition includes determining an Estimated Time of Arrival (ETA) for each munition relative to its determined target seeker basket.

Abstract: An altimeter includes a laser projector for projecting a pattern onto a surface and a camera for viewing the projected pattern. An image processor is operatively connected to the laser projector and camera for determining distance to the surface based on cross-correlation of the projected and imaged patterns. The camera can be a short wave infrared (SWIR) camera. The projected pattern can be a pseudo-random, fixed pattern.
