Data Processing: Vehicles, Navigation, And Relative Location > Navigation > Employing Position Determining Equipment > Using Global Positioning System (gps) > Means To Improve Accuracy Of Position Or Location Means To Improve Accuracy Of Position Or LocationMeans To Improve Accuracy Of Position Or Location patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.11/23/06 - 20060265129 - Method for improving gps integrity and detecting multipath interference using inertial navigation sensors and a network of mobile receivers A method for checking the integrity of GPS measurements for a moving vehicle includes determining a first inter-vehicle distance between a first vehicle and a second vehicle based on GPS measurements obtained at both vehicles, independently determining a second inter-vehicle distance based on relative motion of the first vehicle and ... 10/05/06 - 20060224320 - System and method for assigning pseudo random noise codes to pseudo satellites A pseudolite PRN code assigning system and method are provided. In the system, a management server collects information related to PRN codes of GPS satellites, and a plurality of pseudolites (pseudo satellites) modulate transmission signals with PRN codes assigned from the management server. ... 08/31/06 - 20060195262 - Gps accumulated delta range processing for navigation applications Techniques for GPS navigation used to determine the position and velocity of a moving object. Pseudorange (PR) measurements and accumulated delta range (ADR) measurements are made at the object from received GPS signals. Differences are computed between ADR measurements that are separated by a time interval that is greater than ... 07/06/06 - 20060149472 - Vision-aided system and method for guiding a vehicle A method and system for guiding a vehicle comprises a location determining receiver for collecting location data for the vehicle. A vision module collects vision data for the vehicle. A location quality estimator estimates the location quality data for the location data during an evaluation time window. A vision module ... 03/30/06 - 20060069505 - System and method for detecting interference in global positioning satellite signals A system and method are provided for detecting local interference in GPS signals. A GPS receiver is capable of determining its GPS coordinates. A memory is capable of storing an initial location of the GPS receiver and a user-defined range of error. A processor is programmed to determine whether GPS ... 03/23/06 - 20060064244 - Differential gps corrections using virtual stations Method and apparatus for providing GPS pseudorange correction and carrier phase correction information for navigation or surveying activities over a selected geographic region S of arbitrary size. In a navigation mode, a virtual reference station (VRS), positioned near a selected location L, receives differential GPS (DGPS) correction signals, translates these ... 03/16/06 - 20060058958 - Proximity search methods using tiles to represent geographical zones A proximity search engine for carrying out a proximity search with respect to a reference location uses as a reference frame the earth divided into tiles, which are predefined geographic regions of substantially equal areas. Records that are searched based on proximity to a reference location include location pointers, each ... 12/22/05 - 20050283312 - Method and device for improving gps-based positioning of vehicles on roads A method for estimating an error in GPS signals used by a vehicle estimates an error in the GPS signals received by the vehicle as a function of a difference in a geometry of the GPS signals related to a curved section of the road and a geometry of the ... 10/20/05 - 20050234644 - Positioning and navigation method and system thereof A improved positioning and navigation method and system thereof can substantially solve the problems encountered in global positioning system-only and inertial navigation system-only, such as loss of global positioning satellite signal, sensibility to jamming and spoofing, and inertial solution's drift over time, in which the velocity and acceleration from an ... 10/06/05 - 20050222768 - Satellite navigation controller A navigation device changes a position determination accuracy of a receiver for satellite navigation to a higher accuracy in the following cases: when the subject vehicle approaches a destination, the subject vehicle runs on a road not described in map information, when the subject vehicle approaches an intersection at which ... 08/04/05 - 20050171696 - Location monitoring and transmitting device, method, and computer program product using a simplex satellite transmitter A device, method, and computer program product for monitoring and transmitting a location and a local status of a remote device using a simplex satellite transmitter. The monitoring device includes a position location unit, a simplex satellite transmitter, a power source, and a controller. The position location unit is configured ... 06/30/05 - 20050143916 - Positioning apparatus and method combining rfid, gps and ins Provided is an apparatus and method for positioning a mobile object by combining Radio Frequency Identification (RFID), Global Positioning System (GPS), and Inertial Navigation System (INS). The apparatus and method can acquire positioning information stably and continuously even when GPS signals are cut off by combining the RFID positioning information ... 06/16/05 - 20050131645 - Machine having automatic transport with scanning and gps functions A automatic-transport system with scanning and GPS functions for moving people or objects, on platforms or items placed on an automatic-transport system that can be ejected from it and delivered from one location to another and to return automatically or to proceed to other destination(s) by following GPS coordinates, and ... ### FreshPatents.com Support |
