Patent number: 9408033Abstract: Hybrid location determination for wireless communication device. Various services that may be used by a wireless communication device within a particular location may be referred to as location based services (LBS). As such, means by which the location of a wireless communication device that may use such available services, within such a locale, is made by using more than one type of location determination approach. For example, a wireless communication device includes communication capability (e.g., RX and TX) in accordance with a first communication protocol (e.g., Bluetooth) and also includes a communication capability (e.g., RX only) in accordance with a second communication protocol (e.g., WiFi/WLAN (Wireless Local Area Network)). The RX capability is operative to assist in location determination for the wireless communication device based on knowledge of at least one wireless communication device that communicates with the wireless communication device.Type: GrantFiled: June 2, 2014Date of Patent: August 2, 2016Assignee: BROADCOM CORPORATIONInventors: Brima B.

Patent number: 9020756Abstract: Method and apparatus for processing a satellite positioning system (SPS) signal is described. In one example, a timing reference related to a SPS time of day is obtained from a wireless communication signal received by a mobile receiver. A bias in a local clock of the mobile receiver with respect to a frame timing of a repeating code broadcast by the satellite is compensated for in response to the timing reference. An expected code delay window is obtained for the SPS signal at the mobile receiver. The SPS signal is correlated with a reference code within the expected code delay window. In another example, an expected code delay window is obtained at the mobile receiver. The mobile receiver selects a sampling resolution in response to a size of the expected code delay window. The SPS signal is sampled at the selected sampling resolution and then correlated with a reference code.Type: GrantFiled: May 4, 2004Date of Patent: April 28, 2015Assignee: Global Locate, Inc.Inventors: Charles Abraham, Donald L.

Patent number: 6853916Abstract: A method and apparatus for locating mobile device over a broad coverage area using a wireless communications link that may have large and unknown latency. The apparatus comprises at least one mobile device, a reference network, a position server, a wireless carrier, and a location requester. The mobile device is in communication with the wireless carrier and receives global positioning system (GPS) signals from a plurality of satellites in the GPS satellite constellation. The reference network is coupled to the position server and provides GPS data. The mobile receiver receives GPS signals, performs rudimentary signal processing and transmits the processed signals to the wireless carrier. The wireless carrier passes the signals on to the position server. The position server processes the mobile receiver's GPS data and the reference network ephemeris data to identify the location of the mobile receiver. The location is sent to the location requester.Type: GrantFiled: November 15, 2002Date of Patent: February 8, 2005Assignee: Global Locate, Inc.Inventors: Donald L.

Patent number: 6829534Abstract: A method and apparatus for performing timing synchronization in a mobile device. The method and apparatus include a wireless transceiver having a first oscillatory signal generator (OSG) and a Global Position System (GPS) receiver. The GPS receiver includes a second oscillatory signal generator coupled to a counter for receiving a first clock signal from the first OSG and a second clock signal from the second OSG. Additionally, a GPS signal processor is coupled to the counter. The counter provides a relative offset signal between the first and second oscillatory signal generators to the GPS signal processor for adjusting a pseudo-range model.Type: GrantFiled: January 7, 2003Date of Patent: December 7, 2004Assignee: Global Locate, Inc.Inventors: Donald L.
