Patent number: 10725184Abstract: Methods and apparatuses are provided for use with mode switchable navigation radios and the like. The methods and apparatuses may be implemented to selectively switch between certain operating modes based, at least in part, one or more determinations relating to one or more satellite positioning signals and/or space vehicles.Type: GrantFiled: July 14, 2017Date of Patent: July 28, 2020Assignee: QUALCOMM IncorporatedInventors: Dominic Gerard Farmer, Jie Wu, Lalitaprasad V Daita, Douglas Neal Rowitch, Wyatt Thomas Riley

Publication number: 20170131410Abstract: A mobile device may use one or more outlier detectors to detect likelihoods that an outlier condition exists for a satellite positioning system (SPS) position fix. In some implementations, a method may comprise checking a position fix of a SPS receiver for consistency with assistance data used to generate a position fix. The method may further comprise determining whether to generate a new position fix using less than all of the assistance data based, at least in part, on results of the checking of the position fix.Type: ApplicationFiled: July 19, 2016Publication date: May 11, 2017Inventors: Wyatt Thomas Riley, Lalitaprasad V. Daita, William James Morrison, Dominic Gerard Farmer, Jie Wu

Patent number: 9423505Abstract: A mobile device may use one or more outlier detectors to detect likelihoods that an outlier condition exists for a satellite positioning system (SPS) position fix. In some implementations, an outlier detector may compare a computed position fix to an element of assistance data to generate an outlier likelihood. A decision to perform a recovery operation may be made based, at least in part, on a generated outlier likelihood. In some implementations, a computed reliability of the position fix may also be considered in making a recovery decision.Type: GrantFiled: December 14, 2011Date of Patent: August 23, 2016Assignee: QUALCOMM IncorporatedInventors: Wyatt Thomas Riley, Lalitaprasad V. Daita, William James Morrison, Dominic Gerard Farmer, Jie Wu

Patent number: 8700049Abstract: The subject matter disclosed herein relates to a system and method for reducing an initial position uncertainty of a mobile station. In one example, although claimed subject matter is not so limited, a process to improve an initial position estimate comprises identifying the locations of a serving cell and at least one other landmark proximate to a receiver and determining an initial estimate of the location of the receiver based, at least in part, on the identified locations of the serving cell and the at least one other landmark.Type: GrantFiled: April 18, 2008Date of Patent: April 15, 2014Assignee: QUALCOMM IncorporatedInventors: Marc Ische, Lalitaprasad V. Daita, Thomas K. Rowland

Patent number: 8600297Abstract: Devices and methods are provided for providing self-timing and self-locating in an access point (AP) base station. In one embodiment, the method involves receiving Satellite Positioning System (SPS) signals from a first data source (e.g., plurality of satellites), wherein the SPS signals may include SPS time data, SPS frequency data, and SPS position data. The method may further involve obtaining from a second data source (e.g., cell site, terrestrial navigation station, server, user input interface, etc.) at least one of second time data, second frequency data and second position data, and determining relative reliability of the first and second data sources.Type: GrantFiled: July 28, 2009Date of Patent: December 3, 2013Assignee: QUALCOMM IncorporatedInventors: John W. Ketchum, Srinath Nagaraj, Ashok Bhatia, Eric J. Katzfey, Lalitaprasad V. Daita, Sekharjyoti Baruah

Publication number: 20130027248Abstract: Methods and apparatuses are provided for use with mode switchable navigation radios and the like. The methods and apparatuses may be implemented to selectively switch between certain operating modes based, at least in part, a mode-switching test that takes into consideration one or more non-timed test conditions to determine if mode-switching may be enabled.Type: ApplicationFiled: January 30, 2012Publication date: January 31, 2013Applicant: QUALCOMM IncorporatedInventors: Dominic Gerard Farmer, Jie Wu, Lalitaprasad V. Daita, Douglas Neal Rowitch, Wyatt Thomas Riley

Patent number: 8362951Abstract: Disclosed is an apparatus, system and method for location determination following a search discontinuity utilizing early sampling of a satellite positioning system signal to determine a common code phase offset, pseudorange rate and mode of location calculation.Type: GrantFiled: March 5, 2010Date of Patent: January 29, 2013Assignee: QUALCOMM IncorporatedInventors: Dominic Gerard Farmer, Lalitaprasad V. Daita, Jie Wu

Publication number: 20120206297Abstract: Various techniques are provided which may be implemented in a mobile device to acquire a first positioning signal transmitted by a first transmitter of a first satellite in geostationary orbit, associate the first positioning signal with a coverage region to determine a rough position of the mobile device, and affect a positioning signal search strategy based, at least in part, on the rough position of the mobile device. The search strategy may identify at least one transmitter of at least one satellite in non-geostationary orbit that is estimated to be located in a position to transmit a second positioning signal within at least a portion of the coverage region, and which may be searched for by the mobile device. Such techniques may, for example, reduce a first time to a position fix in certain instances.Type: ApplicationFiled: December 14, 2011Publication date: August 16, 2012Applicant: QUALCOMM IncorporatedInventors: Jie Wu, Lalitaprasad V.
