According to one implementation, the GPS receiving apparatus includes a GPS receiving unit, a storage unit, a position measuring unit, a reception control unit, and a movement judging unit. The storage unit stores GPS information. The reception control unit starts reception operation with a first or second mode. In the first mode, the GPS receiving unit uses the stored GPS information. In the second mode, the stored GPS information is not used. The movement judging unit judges whether the apparatus is moved a predetermined distance or more from a previous measured position. When the movement judging unit judges that the apparatus is moved the predetermined distance or more, the reception control unit starts reception operation with the second mode.Type: GrantFiled: March 3, 2014Date of Patent: June 6, 2017Assignee: CASIO COMPUTER CO., LTD.Inventor: Ryuji Shingyoji

Patent number: 9651672Abstract: A method and system for time synchronization in a mobile device are disclosed. The method includes negotiating a synchronization schedule. The synchronization schedule defines a plurality of synchronization times for receiving synchronization messages. The method further includes transitioning the mobile device from a first state to a second state to receive a synchronization message. The mobile device uses less power in the first state than the second state and the mobile device cannot receive the synchronization message when in the first state. The method further includes synchronizing a clock component in response to receiving the synchronization message.Type: GrantFiled: September 25, 2012Date of Patent: May 16, 2017Assignee: INTEL CORPORATIONInventors: Yaron Alpert, Haim Rochberger

Patent number: 9549289Abstract: A user equipment (UE) communicating with a radio access network (RAN) sends to a network entity (e.g., an MSC/SGSN) a request for periodic reporting of the UE location to a client entity. After the request is approved, the MSC/SGSN sends to the RAN signaling to initiate periodic location reporting for the UE. The RAN may request a positioning center (e.g., a SAS) to send assistance data to the UE. The RAN may coordinate and control the periodic location reporting or may pass the control over to the positioning center. For each location reporting, the UE sends location information (e.g., measurements made by the UE or a location estimate computed by the UE) to the RAN. The SAS computes a location estimate if the UE sends measurements. The RAN then sends the location estimate for the UE to the MSC/SGSN, which forwards the location estimate toward the client entity.Type: GrantFiled: October 5, 2015Date of Patent: January 17, 2017Assignee: QUALCOMM IncorporatedInventors: Stephen William Edge, Sven Fischer, Kirk Allan Burroughs

Patent number: 9490944Abstract: Values representative of modulation signal components are extracted from a modulated signal. The modulated signal contains a modulation signal. A local clock signal is developed which correlates in time to the modulated signal and has a plurality of non-overlapping phase sectors per cycle. The modulated signal is accumulated into an accumulated value, separately for at least one phase sector of one cycle of the local clock signal. Each accumulated value is representative of a modulation signal component. The modulated signal accumulated is of an amount representative of the mathematical integral of the modulated signal during each phase sector of the local clock over which the modulated signal is accumulated.Type: GrantFiled: October 12, 2012Date of Patent: November 8, 2016Inventor: David K Nienaber

Patent number: 9465114Abstract: A module (software or ASIC) for use in a serving mobile Location Center (SMLC) or a mobile station having a GPS receiver (or an A-GPS receiver) for determining an ITOW for a CNAV-1 signal. Also provided is a module for a mobile with GPS (or A-GPS receiver) so that the mobile can use the ITOW (either the ITOW provided with the CNAV-2, or that calculated for the CNAV-1) to uniquely identify ephemeris information in a request for assistance message. Also provided is a module for a SMLC by which the SMLC can use the IOD fields in the assistance data messages in a way that uniquely identifies the associated ephemeris information.Type: GrantFiled: October 26, 2007Date of Patent: October 11, 2016Assignee: Nokia Technologies OyInventors: Jari Syrjärinne, Ismo Halivaara
