Patent number: 11828862Abstract: A personnel location and monitoring system enables on-scene commanders in austere environments to identify, location and manage personnel.

Patent number: 11812510Abstract: Vehicles in traffic cannot coordinate their actions properly in 5G and 6G without knowing the location and the wireless address of the other vehicle. GNSS signals are generally too slow and too imprecise to discern vehicles in, for example, adjacent lanes. Directional wireless beams are subject to reflections from conducting surfaces, producing chaotic signals and false locations if more than one vehicle is within the transmission beam. To provide precise localization in traffic, methods are disclosed for multiple vehicles (or other mobile devices) to acquire satellite signals simultaneously, and then analyze the data differentially, thereby canceling major uncertainties (such as propagation variations, ephemeris motion, and clock jitter), and thereby determining the relative positions precisely. Unlike prior-art “precision” positioning methods, the disclosed methods do not require averaging multiple acquisitions.Type: GrantFiled: February 7, 2023Date of Patent: November 7, 2023Inventors: David E. Newman, R. Kemp Massengill

Patent number: 11582598Abstract: Mobile wireless terminals, such as vehicles in traffic, can determine the relative positions of other vehicles with improved precision by arranging to acquire GNSS (global navigational satellite system) signals simultaneously, and then analyzing the various data sets differentially.

Differential analysis to determine the relative positions of vehicles (as opposed to their overall geographical coordinates) can reduce errors related to satellite ephemeris and velocity, as well as roundoff errors. Localization with a precision of less than 1 meter can greatly improve collision avoidance while discriminating near-miss scenarios from imminent collisions, according to some embodiments. Messaging examples, in 5G and 6G, to manage the simultaneous acquisition and differential analysis, are provided in examples.

Patent number: 11467291Abstract: A method for estimating the pressure measurement bias of a barometric sensor in a wireless terminal. A location engine using the method generates an enhanced estimate of the measurement bias.

The adjustment is based on what is expected as a probable measurement bias value for the particular wireless terminal. Once the location engine generates the enhanced estimate of measurement bias, it can generate improved estimates of elevation of the wireless terminal.Type: GrantFiled: April 21, 2021Date of Patent: October 11, 2022Assignee: Polaris Wireless, Inc.Inventors: Jerome Arthur Blaha, Jr., Scot Douglas Gordon, Jeffrey Noel Wu, Jian Zhu

Patent number: 11402513Abstract: Wireless communication in 5G or 6G, between vehicles (V2V) and other entities (V2X), offers vast opportunities for collision avoidance and improved traffic flow. Many of these opportunities depend on localizing and identifying particular wireless entities (vehicle, pedestrian, base station, toll booth, security gate, among innumerable others). However, due to vehicle motion, the spatial resolution achievable with satellite signals such as GPS, is generally too poor (several meters) to reliably localize a particular wireless entity, inhibiting many applications. Greatly improved localization may be achieved by arranging for multiple vehicles to acquire the satellite signals at the same time from the same satellites. They then transmit parameters of the satellite signals to a calculating entity (such as one of the vehicles) which then processes the data differentially, determining the relative distances between vehicles. Many errors and uncertainties may thereby cancel.Type: GrantFiled: January 25, 2022Date of Patent: August 2, 2022Assignee: AUTONOMOUS ROADWAY INTELLIGENCE, LLCInventors: David E. Newman, R.

Patent number: 11374799Abstract: A method for estimating a wireless communication channel between a transmitter and a receiver, including a plurality of paths for propagation of a wave, at least one of the transmitter and the receiver being formed of a plurality of antennas. The method includes: for at least one path, determining a characteristic matrix, which depends on a first element representative of at least one propagation direction associated with the path, and a second element representative of a propagation distance associated with the path; and estimating the communication channel from the at least one obtained characteristic matrix.Type: GrantFiled: October 9, 2019Date of Patent: June 28, 2022Assignee: FONDATION B-COMInventors: Luc Le Magoarou, Antoine Le Calvez, Stéphane Paquelet

Patent number: 11313973Abstract: A method for determining position of a mobile system, the method includes receiving global navigation satellite (GNSS) signals by a receiver of the mobile system, generating a plurality of position estimates based on at least pseudo-distances determined from at least some of the GNSS signals, wherein each position estimate is generated based on a different set of pseudo-distances, determining an inconsistency in one or more of the position estimates based on verification information, generating a trust assessment for each position estimate based on determined inconsistencies, outputting a position estimate associated with a higher trust assessment as a position of the mobile platform, and reducing an influence of a GNSS signal on a future position estimate generation based on a lower trust assessment for position estimates generated based on the GNSS signal.Type: GrantFiled: April 17, 2019Date of Patent: April 26, 2022Assignee: The MITRE CorporationInventor: Andres D. Molina-Markham

Patent number: 11262457Abstract: System and method for concurrently protecting Iridium and GPS L1/L2 band received satellite signals against interference signals (e.g., jamming signals) using space-time adaptive processing (STAP). While the GPS signal is protected against jamming using Nulling of the interfering signals, the Iridium signal is protected using Beamforming. A single broadband small controlled reception pattern antenna (sCRPA) array receives both the GPS (L1 and L2) and Iridium signals for the STAP-based antijam solutions outputting filtered Iridium and GPS signals. Use of a common (small) broadband antenna and common front end signal processing of the received signals enables an integrated system for use on size, weight, and power constrained platforms such as drones, unmanned aerial vehicles (UAVs), and helicopters.Type: GrantFiled: January 29, 2019Date of Patent: March 1, 2022Assignee: Mayflower Communications Company, INC.Inventors: Christopher Jonathan Zarowski, Huan-Wan Tseng, William LeComte
