Patent number: 10756428Abstract: Systems and methods are provided for performing alignment calibration of an RF antenna in satellite communications. Data is received that is representative of inertial navigation system and gimbal angle measurement signals. The received data is collected while a vehicle is operated in a reduced yaw motion and while the RF antenna is tracking a satellite. Equations are used that describe a mathematical relationship among the misalignments, offsets, and latency mismatch to the antenna gimbal control servo measurements. Estimates are generated for certain errors involved in the alignment process. The generated estimates are provided for pointing the RF antenna.Type: GrantFiled: April 20, 2017Date of Patent: August 25, 2020Assignee: General Dynamics Mission Systems, Inc.Inventor: James M. B.

Publication number: 20200252318Abstract: A signal generator outputs a reference signal corresponding to at least one wireless signal according to the predefined signal encoding to a channel emulator processor. The channel emulator processor is programmed to use at least one synthesized channel parameter and the reference signal to produce and store a perturbed signal as data for training machine learning and artificial intelligence systems. The synthesized channel parameter is synthesized using a channel synthesizer processor programmed to: ingest map elevation data, reference a transmitter and a receiver to the map elevation data, and perform ray tracing of a representative signal between the transmitter and the receiver, while applying at least one predetermined perturbation property to synthesize at least one channel parameter.Type: ApplicationFiled: January 17, 2020Publication date: August 6, 2020Applicant: General Dynamics Mission Systems, Inc.Inventors: John Kleider, Joao Baiense, Chris Morgan

Patent number: 10643123Abstract: The present invention is directed to systems and methods for detecting objects in a radar image stream. Embodiments of the invention can receive a data stream from radar sensors and use a deep neural network to convert the received data stream into a set of semantic labels, where each semantic label corresponds to an object in the radar data stream that the deep neural network has identified. Processing units running the deep neural network may be collocated onboard an airborne vehicle along with the radar sensor(s). The processing units can be configured with powerful, high-speed graphics processing units or field-programmable gate arrays that are low in size, weight, and power requirements. Embodiments of the invention are also directed to providing innovative advances to object recognition training systems that utilize a detector and an object recognition cascade to analyze radar image streams in real time.Type: GrantFiled: May 11, 2018Date of Patent: May 5, 2020Assignee: General Dynamics Mission Systems, Inc.Inventor: John Patrick Kaufhold

Patent number: 10508000Abstract: A cable containing an optical fiber is used to transmit data between an underwater remotely operated vehicle (ROV) and a support vessel floating on the surface of the water. The ROV stores the cable on a spool and releases the cable into the water as the ROV dives away from the support vessel. The ROV detects the tension in the cable and the rate that the cable is released from the ROV is proportional to the detected tension in the cable. After the ROV has completed the dive and retrieved by the support vessel, the cable can be retrieved from the water and rewound onto the spool in the ROV.Type: GrantFiled: May 19, 2016Date of Patent: December 17, 2019Assignee: GENERAL DYNAMICS MISSION SYSTEMS, INC.Inventors: Graham Hawkes, Charles Chiau, Adam Wright

Patent number: 9951840Abstract: A method and an assembly for absorbing energy during an overload event. An energy absorber reduces loads on an object being transported on a loading unit during a single overload event, which introduces such a high degree of energy that there is an overwhelming likelihood the object would be damaged without an energy absorber. Measurement values on the current state of the loading unit are sensed. A control device determines an overload event and a damping of the energy absorber is set to a high value after the detection of the overload event. The damping is maintained for a specified prolonged time period and controlled dependent on the measurement values during the overload event to increase the load for objects during the specified time period initially to a specified threshold load and after the specified time dependent on the measurement values detected during the overload event.Type: GrantFiled: March 13, 2015Date of Patent: April 24, 2018Assignee: General Dynamics European Land Systems-Mowag GmbHInventors: Stefan Battlogg, Markus Mayer
