Patent number: 11777207Abstract: A virtual phased-array and associated methods are disclosed for coherent transmission and/or reception of radio signals among antenna elements of the array, where the antenna elements are wirelessly interconnected and one or more of the elements may be moving. In one embodiment, clocks of the antenna elements are synchronized based on a first set of measurements of wireless signal(s) transmitted by one or more of the antenna elements. Relative positions and orientations of the antenna elements are determined based on a second set of measurements of wireless signal(s) transmitted after the synchronizing of the clocks. Weight(s) of a manifold vector are determined based on the relative positions and orientations, to calibrate the manifold vector. A plurality of coherent wireless signals are transmitted via two or more of the antenna elements based on the calibrated manifold vector.Type: GrantFiled: July 9, 2020Date of Patent: October 3, 2023Assignee: ENSCO, Inc.Inventors: Daniel Thomas Goff, William Todd Faulkner, Michael Lee Picciolo

Patent number: 10094908Abstract: A geolocation system includes an originator device configured to transmit a first wireless signal to a transponder device. The transponder device is configured to transmit a second wireless signal to the originator device. The system includes at least one observer device configured to receive the first wireless signal from the originator device and receive the second wireless signal from the transponder device. The system also includes a first processor configured to calculate a transactional difference range at the at least one observer device based on the first wireless signal received at the observer device and the second wireless signal received at the observer device. A corrected transactional difference range value may be calculated by subtracting a time-of-flight of the first wireless signal from the originator device to the transponder device from the transactional difference range. A method of performing geolocation using a transactional difference range is also disclosed.Type: GrantFiled: May 2, 2017Date of Patent: October 9, 2018Assignee: ENSCO, INC.Inventors: David W. A. Taylor, Jr., Bradley David Farnsworth, William Todd Faulkner
