Publication number: 20100302095Abstract: A system for sharing GPS protocol data is described. In the system, raw GPS protocol data from a satellite is obtained by a GPS receiver. A GPS protocol data server is connected to the GPS receiver through a physical serial port, so as to obtain the GPS protocol data. A service application program is execute on the GPS protocol data server, and provides a service of resolving the GPS protocol data or converting the format thereof through a TCP/IP based multi-thread communication procedure. A virtual serial port driver is used to generate a plurality of virtual serial ports, and each virtual serial port communicates with the service application program through the TCP/IP protocol. Therefore, application devices or application programs respectively communicates with the service application program through the virtual serial ports, thereby obtaining the service of parsing the GPS protocol data provided by the service application program.Type: ApplicationFiled: June 2, 2009Publication date: December 2, 2010Applicant: MITAC TECHNOLOGY CORP.Inventor: Chia-Chin Yu

Publication number: 20100265127Abstract: A method, apparatus and system for time management in a position-location system is described. The method may include (i) obtaining, at a global-navigation-satellite-system receiver while being served by a first node of a wireless network a first time base, a relative-time difference, and a third time base; and forming a time relation as a function of the first time base, relative-time difference (“RTD”) and third time base. The first time base is associated with the first node, and may be, for example, a time base associated with an air interface for communicating with the first node. The RTD may be a difference between the first time base and a second time base associated with a second node of the wireless network. The third time base is associated with a constellation of satellites, and may be, for example, an absolute time associated with the constellation of satellites. The method may include using knowledge of a GNSS time to enhance sensitivity or time to first position of a GNSS receiver.Type: ApplicationFiled: November 30, 2009Publication date: October 21, 2010Inventor: Javier de Salas

Publication number: 20100232351Abstract: The present invention provides methods of improving GNSS receivers' satellite signal acquisition and TIFF performances by taking advantage of SBAS signals. Due to a SBAS satellite's geostationary position and typically strong signal, the SBAS satellite signal can be acquired more quickly than a GPS satellite signal. Once a SBAS satellite signal is acquired the Doppler frequency search uncertainty may be reduced for remaining GNSS satellites which are to be acquired. Furthermore, a satellite search list may be optimized to search for satellites close to the line of sight (LOS) of the SBAS satellite for which a signal has been acquired, in receiver “warm” and “hot” start modes. Moreover, since a SBAS signal sub-frame is only one second long, which is shorter than six seconds for a GPS signal sub-frame, synchronization of the SBAS signal sub-frame may be achieved faster than for GPS signals.Type: ApplicationFiled: March 11, 2009Publication date: September 16, 2010Inventors: Mangesh CHANSARKAR, Gang Xie, Gengsheng Zhang

Publication number: 20100216432Abstract: A wireless location tracking device (WLTD) includes a global position system (GPS) for receiving signals and generating data for determining a geographic location of the wireless location tracking device (WLTD). The WLTD further includes a transceiver for receiving an incoming call from a caller requesting a location of the wireless location tracking device. A processor includes a map database for receiving and applying data from the GPS to determine a geographic location of the WLTD in reference to the map database. The processor further controls the transceiver to automatically call back the caller for transmitting a short message to indicate the geographic location of the WLTD.Type: ApplicationFiled: February 11, 2010Publication date: August 26, 2010Inventor: Raymound Wu

Patent number: RE43620Abstract: A system for improving the operation of a GPS based navigator. Statistical and/or time of day information is used to select the best route between a current location and a desired location. The statistical information may take into account anomalies, and a user can select the amount of risk they which take. The system can be updated with more updated information. In addition, the selection of the desired location can be carried out by downloading information from a PDA.Type: GrantFiled: April 9, 2011Date of Patent: August 28, 2012Inventor: Scott C. Harris
