Inertial Sensor Aided Heading And Positioning For Gnss Vehicle Navigation

View page
US Patent:
20120173142, Jul 5, 2012
Filed:
Dec 1, 2011
Appl. No.:
13/309520
Inventors:
Joseph CZOMPO - Santa Clara CA, US
Guttorm Ringstad OPSHAUG - San Diego CA, US
Kumar Gaurav CHHOKRA - San Jose CA, US
Zoltan Fenene BIACS - San Mateo CA, US
Wyatt T. RILEY - Chesterbrook PA, US
Assignee:
QUALCOMM INCORPORATED - San Diego CA
International Classification:
G01C 21/10
US Classification:
701501
Abstract:
An apparatus and method for providing an improved heading estimate of a mobile device in a vehicle is presented. First, the mobile device determines if it is mounted in a cradle attached to the vehicle; if so, inertia sensor data may be valid. While in a mounted stated, the mobile device determines whether it has been rotated in the cradle; if so, inertia sensor data may no longer be reliable and a recalibration to determine a new relative orientation between the vehicle and the mobile device is needed. If the mobile device is mounted and not recently rotated, heading data from multiple sensors (e.g., GPS, gyroscope, accelerometer) may be computed and combined to form the improved heading estimate. This improved heading estimate may be used to form an improved velocity estimate. The improved heading estimate may also be used to compute a bias to correct a gyroscope.

Pejman Lotfali Kazemi - Cupertino CA, US
International Classification:
G01L 27/00
H04W 4/02
H04W 4/38
H04W 4/90
Abstract:
Described herein are techniques to enable a mobile device to perform multi-source estimation of an altitude for a location. A baseline altitude may be determined at ground level for a location and used to calibrate a barometric pressure sensor on the mobile device. The calibrated barometric pressure sensor can then estimate changes in altitude relative to ground level based on detected pressure differentials, allowing a relative altitude to ground to be determined. Baseline calibration for the barometric sensor calibration can be performed to determine an ambient ground-level barometric pressure.

Location Source Control

US Patent:
20210144786, May 13, 2021
Filed:
Jan 22, 2021
Appl. No.:
17/156107
Inventors:
- Cupertino CA, US
Glenn Donald MacGougan - San Jose CA, US
Kumar Gaurav Chhokra - San Jose CA, US
Robert Mayor - Half Moon Bay CA, US
Ronald K. Huang - San Jose CA, US
Stephen J. Rhee - San Jose CA, US
International Classification:
H04W 76/14
H04W 4/029
Abstract:
Techniques for location source control for paired devices are described. Location source control selects a location source for a mobile device. The mobile device can receive, from an application program, a request for determining a location of the mobile device. The mobile device can determine a first location estimate using a location subsystem of the mobile device. The mobile device can determine whether to provide the first location estimate as input to the application program, or to provide a second location estimate as input to the application program. The second location estimate can be an estimated location of the companion device and determined by the companion device.

US Patent:
20170357005, Dec 14, 2017
Filed:
Sep 23, 2016
Appl. No.:
15/275299
Inventors:
- Cupertino CA, US
Glenn Donald MacGougan - San Jose CA, US
Kumar Gaurav Chhokra - San Jose CA, US
Robert Mayor - Half Moon Bay CA, US
Yishuang Geng - Worcester MA, US
Assignee:
Apple Inc. - Cupertino CA
International Classification:
G01S 19/10
G01S 19/42
G01S 19/21
Abstract:
Techniques for improving positioning performance using categorization of navigation signal environment are described. A mobile device can receive signal environment data. The signal environment data can represent multiple geographic areas. The signal environment data includes a respective signal environment category for each geographic area, each signal environment category corresponding to a degree to which geographic features in the respective geographic area affect reception of the navigation signals. The mobile device can determine that the mobile device is located in a particular geographic area represented in the signal environment data. The mobile device can then select a set of one or more rules for aiding location estimation. The set of one or more rules can correspond to the signal environment category of the geographic area. The mobile device can estimate a location of the mobile device using the navigation signals and under the set of one more rules.

US Patent:
20170013407, Jan 12, 2017
Filed:
Jul 13, 2016
Appl. No.:
15/209703
Inventors:
- Cupertino CA, US
Robert W. Mayor - Half Moon Bay CA, US
Kumar Chhokra - San Mateo CA, US
Assignee:
APPLE INC. - Cupertino CA
International Classification:
H04W 4/02
G01S 19/28
H04B 7/185
Abstract:
A mobile device adjusts the extents to which it depends on various satellites to estimate its global position based on the predicted probability for each such satellite that a ray extending from that satellite to the mobile device is obstructed by a building. The mobile device can predict the probabilities of building obstructions based on a digital model of the environment in which the mobile device is estimated to be. The mobile device weights the extent of uncertainty for each satellite's global positioning data based on the predicted probability of obstruction for that satellite. Using these weighted uncertainties, the mobile device selects the extents to which it relies on each satellite's global positioning data when estimating the mobile device's current global position.

International Classification:
H04W 4/02
G01C 5/06
H04W 4/22
Abstract:
Apparatus and methods for estimating a location of a wireless device in communication with a wireless network, such as a UMTS network, based at least in part on WLAN/WPAN AP measurements and/or barometric measurements are disclosed. The wireless device responds to a location capability inquiry from the wireless network by providing a response that indicates the wireless device is configurable to estimate its location based on WLAN/WPAN AP and/or barometric measurements. The wireless network sends WLAN/WPAN AP and/or barometric reference information to the wireless device to assist in estimating its location. The wireless device measures one or more WLAN/WPAN APs, and the wireless device uses the WLAN/WPAN AP and/or barometric measurements to estimate its location. In some embodiments, GPS/GNSS information is used in conjunction with WLAN/WPAN AP and/or barometric measurements to estimate the location of the wireless device.
