Patent number: 8078189Abstract: In a method for providing location-based information over a network, a plurality of GPS reference data sets, corresponding to a plurality of respective local areas, are acquired at intervals such that each GPS reference data set is updated on a continuous basis. A plurality of aiding data sets are generated at intervals based on the respective GPS data sets, whereby each aiding data set is updated on a continuous basis. The generated aiding data sets are stored at intervals on a data-storing network server, whereby updated aiding data sets are available on a continuous basis for access by a requesting entity via communication with the data-storing network server.Type: GrantFiled: March 24, 2005Date of Patent: December 13, 2011Assignee: Sirf Technology, Inc.Inventors: Steve Chang, Ashutosh Pande, Lionel Jacques Garin, Kanwar Chadha, Leon Kuo-Liang Peng, Gengsheng Zhang, Nicolas Patrick Vantalon, Gregory Turetzky

Patent number: 7970412Abstract: An Aided Location Communication System (“ALCS”) is described that may include a geolocation server and a wireless communication device having a GPS section where the GPS receiver section is capable of being selectively switched between a standalone mode and at least one other mode for determining a geolocation of the wireless communications device. An Aided Location Communication Device (“ALCD”) is also described. The ALCD includes a position-determination section having a GPS receiver and a communication section where the position-determination section is selectively switchable between a GPS-standalone mode and at least one other mode for determining a geolocation of the ALCD.Type: GrantFiled: July 20, 2005Date of Patent: June 28, 2011Assignee: SiRF Technology, Inc.Inventors: Ashutosh Pande, Lionel Jacques Garin, Kanwar Chadha, Kurt Christian Schmidt, Leon Kuo-Liang Peng, Gengsheng Zhang, Nicolas Patrick Vantalon, Gregory B.
