The detector, when the platform is at a first location, measures a characteristic of the jamming signal. The platform and its detector are then moved to a chosen second location, from which a further measurement of the jamming signal is made. The measurements made by the detector are then used to determine the location of the source of the jamming signal.Type: ApplicationFiled: September 4, 2014Publication date: December 1, 2016Applicant: MBDA UK LIMITEDInventors: Colin Aaron LITTLEFIELD, Timothy WHITWORTH, Yeqiu YING, Graham Patrick WALLIS, Mark DUMVILLE

Publication number: 20160349376Abstract: Systems, methods and non-transitory, computer-readable storage mediums are disclosed for a multimode GNSS odometer. In some implementations, a method comprises: obtaining, by a device, position and velocity data from a sensor embedded in, or coupled to the device; statistically combining, by the device, the position and velocity data to generate a first delta distance travelled by the device over a period of time, the statistical combining including weighting a contribution of an integrated speed to the first delta distance, the integrated speed derived from the obtained velocity data and period of time; filtering, by the device, the first delta distance to generate a filtered first delta distance; and generating, by the device, a first estimate of total distance travelled by the device based on the filtered first delta distance.Type: ApplicationFiled: August 27, 2015Publication date: December 1, 2016Inventors: Pejman Lotfali Kazemi, Glenn Donald MacGougan

Publication number: 20160349377Abstract: The disclosure describes methods of managing the power consumption of a GNSS receiver by identifying when to activate and deactivate the GNSS receiver, and by managing storage of GNSS location data points. In one embodiment, the GNSS receiver is activated if there is a change in wireless transmissions from stationary sources. In another embodiment, the GNSS receiver is deactivated when the GNSS signal quality is sufficient to calculate a GNSS location. In another embodiment, the GNSS receiver is deactivated for a time period in correlation with a GNSS speed. In yet another embodiment, redundant GNSS location data points are identified and only non-redundant data points are stored. In yet another embodiment, a GNSS device comprises a processor and a GNSS receiver configured to track GNSS signals and calculate a GNSS location. The GNSS receiver deactivates when the average signal quality value meets or exceeds the baseline signal value.Type: ApplicationFiled: May 25, 2015Publication date: December 1, 2016Inventors: Perry Jarmuszewski, George Mankaruse, Rongrong Zhang

Publication number: 20160349378Abstract: The present disclosure is directed to power conservation via global navigation satellite system (GNSS)-cellular activity synchronization. In general, power may be conserved in a device by setting a GNSS module in a device to operate during a time period when communication resources (e.g., a communication module) in the device are already scheduled to operate, which may conserve power in the device. Synchronization may occur via a notification (e.g., a pulse, a message, etc.) that is transmitted from the communication module to the GNSS module. In this manner, the burden of managing GNSS module operation may be shifted from control resources in the device (e.g., a system module) to the communication module, allowing the system module to remain in a power conservation state (e.g., sleep state) for longer durations and for GNSS signal measurement to occur when the system module is already active.Type: ApplicationFiled: May 26, 2015Publication date: December 1, 2016Applicant: Intel IP CorporationInventor: Raghvendra GUPTA

Publication number: 20160349379Abstract: An atomic clock is used in conjunction with the GNSS receiver and the inertial sensors, creating a more capable inertial navigation system (INS). The system is composed of a GNSS receiver, an accurate clock, and a mechanism for measuring relative pose changes. The system being presented utilizes an inertial measurement unit (IMU) to provide the relative pose changes, but other mechanisms can be used—like visual and ladar odometry. The GNSS receiver measures the pseudo-ranges to the GNSS satellites in the field of view. These measurements are “time tagged” with the accuracy of the atomic clock. The relative motion between the pseudo-ranges is measured using the IMU. Finally, the lock is achieved by filtering these measurements. The filtering mechanism can vary, from the traditional Kalman Filters to other mechanisms that attempt to minimize the mean square error.Type: ApplicationFiled: May 31, 2016Publication date: December 1, 2016Inventors: Alberto Daniel Lacaze, Karl Nicholas Murphy, Raymond Paul Wilhelm, III

Publication number: 20160349380Abstract: A pulse detection circuit according to an embodiment includes a conversion circuit, a delay circuit, first and second comparators, a latch, and a generation circuit. The conversion circuit converts an input signal into a thermometer code signal. The delay circuit outputs a delay signal being the thermometer code signal delayed by a predetermined delay time. The first comparator (The second comparator) compares the thermometer code signal with the delay signal and outputs an increase signal (a decrease signal) indicating whether the input signal is larger (smaller) than the input signal before the delay time. Based on the increase signal and the decrease signal, the latch outputs an increase-decrease signal indicating whether the input signal is increasing or decreasing. Based on the thermometer code signal and the increase-decrease signal, the generation circuit generates a pulse detection signal and a pileup detection signal.Type: ApplicationFiled: May 26, 2016Publication date: December 1, 2016Applicant: Kabushiki Kaisha ToshibaInventors: Hirokatsu SHIRAHAMA, Tetsuro Itakura, Masanori Furuta, Shunsuke Kimura, Go Kawata, Hideyuki Funaki
