Patent number: 11920899Abstract: 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.Type: GrantFiled: January 18, 2022Date of Patent: March 5, 2024Assignee: Rosemount Aerospace Inc.Inventors: Guy Squillace, Gary Willenbring, Todd A.

Patent number: 11913757Abstract: 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.Type: GrantFiled: January 18, 2022Date of Patent: February 27, 2024Assignee: Rosemount Aerospace Inc.Inventors: Guy Squillace, Gary Willenbring, Todd A.

Publication number: 20230228528Abstract: A method including obtaining at each of a plurality of nodes navigation data of the node, communicating at each node its navigation data to the other nodes via each node's datalink communication system, receiving at each node navigation data communicated from the other nodes, determining at each node distance range of the node relative to the other nodes for which navigation data was received, determining at each node a constellation of the nodes as a function of the navigation data of the node, the navigation data received from the other nodes, and the distance range of the node relative to the other nodes, accessing formation constraints to form the constellation at each node, calculating at each node first guidance commands to maneuver the node to adjust the constellation to be in compliance with the formation constraints; and navigating each node to execute a maneuver based on the first guidance commands.Type: ApplicationFiled: January 18, 2022Publication date: July 20, 2023Applicant: Rosemount Aerospace Inc.Inventors: Guy Squillace, Gary Willenbring, Todd A.

Publication number: 20230229175Abstract: 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.Type: ApplicationFiled: January 18, 2022Publication date: July 20, 2023Applicant: Rosemount Aerospace Inc.Inventors: Guy Squillace, Gary Willenbring, Todd A.

Publication number: 20220065588Abstract: A course correction system for a projectile can include a pre-steering trajectory determination module. The pre-steering trajectory determination module can be configured to receive a series of possible trajectories from an estimation module including a physical model defining trajectory as a function of gravitational pull and one or more launch variables, and receive a sensor data from one or more on-board sensors of the projectile. The pre-steering trajectory determination module can also be configured to reduce the possible trajectories from the estimation module to one or more refined trajectories using the sensor data, and output the one or more refined trajectories.Type: ApplicationFiled: August 31, 2021Publication date: March 3, 2022Applicant: Simmonds Precision Products, Inc.Inventors: Gary Willenbring, Gregory Nash, Guy Squillace
