Publication number: 20170363423Abstract: Calibrating an unstable sensor of a mobile device. Systems and methods for calibrating a sensor of a mobile device determine a first estimated position of the mobile device without using any measurement from the sensor of the mobile device, generate a second estimated position of the mobile device using a measurement from the sensor, estimate a sensor error of the sensor using the first estimated position and the second estimated position, and use the sensor error to determine a calibration value for adjusting one or more measurements from the sensor.Type: ApplicationFiled: August 31, 2017Publication date: December 21, 2017Inventors: Michael DORMODY, Ganesh PATTABIRAMAN, Abijith KUMAR, Thomas WOLF, Gary PARSONS, Christian GATES, Deepak JOSEPH, Badrinath NAGARAJAN

Publication number: 20170338855Abstract: Systems and methods are described for determining position of a receiver. The positioning system comprises a transmitter network including transmitters that broadcast positioning signals. The positioning system comprises a remote receiver that acquires and tracks the positioning signals and/or satellite signals. The satellite signals are signals of a satellite-based positioning system. A first mode of the remote receiver uses terminal-based positioning in which the remote receiver computes a position using the positioning signals and/or the satellite signals. The positioning system comprises a server coupled to the remote receiver. A second operating mode of the remote receiver comprises network-based positioning in which the server computes a position of the remote receiver from the positioning signals and/or satellite signals, where the remote receiver receives and transfers to the server the positioning signals and/or satellite signals.Type: ApplicationFiled: July 27, 2017Publication date: November 23, 2017Inventors: ARUN RAGHUPATHY, GANESH PATTABIRAMAN, SUBRAMANIAN S. MEIYAPPAN

Publication number: 20160003949Abstract: Systems and methods for estimating whether a receiver is indoors or outdoors. Certain approaches evaluate data associated with a network of beacons to determine whether the receiver is indoors or outdoors. Such evaluation may include any of determining whether azimuthal angles corresponding to the beacons meet an azimuthal angle condition, determining whether elevation angles corresponding to the beacons meet an elevation angle condition, determining whether signal strengths corresponding to the beacons meet a signal strength condition, and determining whether other measurements associated with the beacons meet other measurement conditions.Type: ApplicationFiled: June 24, 2015Publication date: January 7, 2016Inventors: Jagadish Venkataraman, Ganesh Pattabiraman
