Patent number: 10534088Abstract: A method and system for assisting mobile stations to locate a satellite use an efficient messaging format. A server computes a correction between coarse orbit data of a satellite and precise orbit data of the satellite. A coordinate system is chosen such that variation of the correction is substantially smooth over time. The server further approximates the correction with mathematical functions to reduce the number of bits necessary for transmission to a mobile station. The mobile station, upon receiving the coefficients, evaluates the mathematical functions using the coefficients and a time of applicability (e.g., the current time), converts the evaluated result to a standard coordinate system, and applies the conversion result to the coarse orbit data to obtain the precise orbit data.Type: GrantFiled: October 7, 2015Date of Patent: January 14, 2020Assignee: QUALCOMM IncorporatedInventors: Michael James Wengler, Leonid Sheynblat, Mark Leo Moeglein, Zoltan F.

Patent number: 8380458Abstract: An apparatus and method for detecting whether a mobile device is in flight based on sensor measurements from a 3-dimensional accelerometer are presented. For example, embodiments estimate a direction of gravity and non-gravity acceleration, separate this non-gravity acceleration into a vertical and horizontal components, then test the estimated accelerations to determine whether the mobile device is experiencing sufficient vertical acceleration to warrant an in-flight determination.Type: GrantFiled: March 18, 2010Date of Patent: February 19, 2013Assignee: Qualcomm IncorporatedInventor: Michael James Wengler

Patent number: 8289159Abstract: The location of a device may be determined with respect to another device. For example, a locating device may be moved as it measures at least one distance to a target device. The locating device may then generate one or more indications relating to the measured distance or distances. The locating device also may generate one or more indications relating one or more determined directions to the target device. The target device may be moved in a predetermined manner to determine the location of the target device. Each of the devices may employ a single transceiver and a single antenna for the location determination operations.Type: GrantFiled: April 24, 2007Date of Patent: October 16, 2012Assignee: QUALCOMM IncorporatedInventors: David Jonathan Julian, Chong U.

Patent number: 7859461Abstract: A method for detecting a plurality of navigation beacon signals by using either two antennas or a synthetic aperture antenna for receiving a plurality of distinct measurements, and combining the plurality of distinct measurements using a plurality of antenna weight components to form an interference cancellation beam. In one embodiment, the plurality of antenna weight components is determined by eigenvalue processing. In another embodiment, the plurality of antenna weight components is determined by simplified processing. In another aspect, a single antenna is used for receiving an originally received measurement. A copy of the originally received measurement is made and processed to achieve the proper time delay to emulate spatial diversity. The originally received measurement and the processed copy are combined to form an interference cancellation beam.Type: GrantFiled: April 4, 2008Date of Patent: December 28, 2010Assignee: QUALCOMM IncorporatedInventors: Michael James Wengler, Ahmad Jalali

Patent number: 7792225Abstract: A method and device for combating cross-correlation false alarms by introducing code diversity in the correlation process in which the search code may be diversified by the use of code staggering and/or code scrambling. The energy levels of the signals before and after the search code have been diversified may be evaluated to detect a false alarm. In addition, a set of parameterized analytical models may be used to estimate the rate of false alarms from cross-correlation in wireless networks in order to guide development and design of wireless transceivers.Type: GrantFiled: November 29, 2006Date of Patent: September 7, 2010Assignee: QUALCOMM IncorporatedInventors: Cristina A.
