| 20100238070 | SYSTEM AND METHOD FOR CONCURRENTLY DETERMINING LOCATIONS OF MOBILE DEVICE IN WIRELESS COMMUNICATION NETWORK - A method for a mobile location center (MLC) to determine a location of a mobile device in a wireless communication network includes receiving a request to determine the location of the mobile device; concurrently requesting global navigation satellite system (GNSS) measurements from the mobile device and terrestrial measurements from transceivers in the wireless communication network, and receiving the GNSS measurements and at least one of the terrestrial measurements. A GNSS location of the mobile device is calculated as a function of the GNSS measurements, and the calculated GNSS location is determined to be the location of the mobile device when the calculated GNSS location meets a predetermined accuracy threshold. A terrestrial location of the mobile device is calculated as a function of the terrestrial measurements, and the calculated terrestrial location is determined to be the location of the mobile device when the calculated terrestrial location meets the predetermined accuracy threshold. | 09-23-2010 |
| 20100277365 | MOBILE TERMINAL TO PROVIDE LOCATION MANAGEMENT USING MULTIMEDIA DATA AND METHOD THEREOF - A mobile terminal to manage a location using multimedia data and a method thereof are disclosed. The mobile terminal acquires a Global Positioning System (GPS) satellite signal in a camera preview and utilizes the GPS satellite signal in a map service in association with multimedia data. In addition, the mobile terminal acquires and stores place name information from a location guide service using location information, and provides a service using the location information stored in the multimedia data. | 11-04-2010 |
| 20100302099 | System and method for geo-locating a receiver with reduced power consumption - A system and process for the geo-location of an asset given no a priori knowledge regarding time and location of the asset with minimized power consumption is disclosed. In the preferred embodiment, the system is accurate to about 30 meters CEP (50% circular error probable) using just a short segment, e.g., 100-200 ms, of digitized GPS L1 signal data. | 12-02-2010 |
| 20110273330 | Method and System for Customized Full Ephemeris Compatible With Standard AGPS Network Devices - Aspects of a method and system for customized full ephemeris compatible with standard AGPS network devices allows a GPS enabled handset to receive real-time full ephemeris from an AGPS server for calculating a position fix. The real-time full ephemeris may be generated at the AGPS server in response to one or more request for real-time full ephemeris from the GPS enabled handset. The AGPS server may be configured to provide fresh full ephemeris generated at smaller intervals such as every 10-15 minutes as approximated real-time full ephemeris. The generated real-time full ephemeris or fresh full ephemeris may be communicated to the GPS enabled handset periodically or aperiodically. Various predicted real-time full ephemeris or predicted fresh full ephemeris compatible with various standards may be generated via Short Term Orbits (STO) technology. | 11-10-2011 |
| 20120032844 | REAL-TIME LOCATION TRACKING APPARATUS AND METHOD USING GLOBAL POSITIONING SYSTEM (GPS) SIGNAL RELAY TAG - Real-time location tracking apparatus and method using a global positioning system (GPS) signal relay tag is provided. Here, a tag may receive a GPS signal and transmit the received GPS signal to a reader, and the reader may calculate a location of the tag, and thereby a real-time location tracking service may be provided. | 02-09-2012 |
| 20120319896 | GEOLOCATION SYSTEM AND METHOD HYBRIDIZING A SATELLITE NAVIGATION SYSTEM AND A DATA COLLECTION SYSTEM - Method of geolocation employing hybridization of a satellite navigation system and a data collection system. The method minimizes processing time by the means equipping the objects to be geolocated, given the processing effected in “masked time” by remote equipment, typically ground stations of the data collection system. To this end, the method necessitates only acquisition of the code phase of the positioning information coming from the satellite navigation system. | 12-20-2012 |
| 20130021200 | System and Method for Dual-Mode Location Determination - A geographic tracking system with minimal power and size required at the mobile terminal collects observation data at the mobile terminal, forwards the data to a processor, which calculates the position. The mobile terminal needs only to gather a few milliseconds of observation data, and to relay this observation data to the processor. In one embodiment, the observation data is communicated to the processor using either a satellite communication network or through a mobile telephone network. | 01-24-2013 |
| 20140145878 | POSITIONING SYSTEMS - A method is provided whereby a group of receivers local to one another make GNSS measurements of a number of satellites, from one or multiple different GNSS's, and by combining the measurements of the same satellites made by the different receivers it is possible given sufficient conditions to determine the positions of the receivers and the satellite errors such that the positions obtained are equivalent to those obtained from a traditional differential GNSS system, without the need for a static reference receiver at a known location. | 05-29-2014 |
| 20160109576 | Method for reducing a risk of tampering and/or spoofing of location data of an object over time, and use of signals-in-space receiver and reader in such method - The invention relates to a method and system for retrieving location data of an object, the location data being representative of position, velocity and time. The method comprises the step of providing a signals-in-space receiver to the object. The receiver comprises an antenna for receiving an encrypted navigation signal, an A/D converter for discretizing the encrypted navigation signal into encrypted navigation data, a memory unit for storing the encrypted navigation data and an interface for connecting a reader to the memory unit. The method comprises the steps of receiving the encrypted navigation signal by the antenna and discretizing the encrypted navigation signal into encrypted navigation data. The method comprises the step of storing the encrypted navigation data in the memory unit and connecting the reader with the memory unit for transferring the encrypted navigation data from the memory unit to the reader and the step of decrypting in the reader the encrypted navigation data and retrieving the location data of the object. | 04-21-2016 |
| 20160146947 | SIGNAL PROCESSING - A method of processing signal data including an unencrypted portion and an encrypted portion, the method including: receiving, at a receiver, the signal data; processing a sample of the signal data to provide a processed signal sample including data relating to the encrypted portion of the signal data and data relating to the unencrypted portion of the signal data, comparing the unencrypted signal data with at least one reference signal to determine information including at least one of (i) the time at which the signal was sent from the source and (ii) the identity of the source; requesting, based on the determined information, and from a source remote to the receiver, a set of encrypted reference signal samples; comparing, on a processing device remote to the receiver, the set of encrypted reference signal samples with the received encrypted signal data to identify any matching signal samples. | 05-26-2016 |
