Compass Calibration

View page
US Patent:
20130262011, Oct 3, 2013
Filed:
Mar 28, 2012
Appl. No.:
13/433082
Inventors:
Scott J. Graybill - Christchurch, NZ
Farshad Nourozi - Rolleston, NZ
Shawn D. Weisenburger - Denver CO, US
International Classification:
G06F 19/00
US Classification:
702 96, 702 85
Abstract:
A system, method, and computer program product are provided for calibrating a sensor device, such as an accelerometer, gyroscope, and/or magnetometer. The sensor device provides measurements, and a determination if the sensor device is in a steady state is made based at least partly on the measurements. If the sensor device is in a steady state then measurement data is stored in a memory, and the sensor device is calibrated at least partly with the stored data. A set of such steady points is gathered with the sensor device in various spatial orientations, preferably with the steady point orientations spaced appropriately apart to ensure precise calibration throughout the range of possible orientations. Calibration parameters are determined by fitting the set of steady point measurements to an ellipsoid. Active audio and visual guidance may be provided to a user to assist with orienting the sensor device during calibration.

US Patent:
20130243250, Sep 19, 2013
Filed:
Mar 14, 2013
Appl. No.:
13/829085
Inventors:
Shawn D. Weisenburger - Denver CO, US
Assignee:
TRIMBLE NAVIGATION LIMITED - Sunnyvale CA
International Classification:
G06K 9/46
US Classification:
382103
Abstract:
A method for matching a region on an object of interest with a geolocation in a coordinate system is disclosed. In one embodiment, an image of a region on an object of interest is captured on an image capture device. The image is processed to detect a located feature using a feature detection algorithm. Further processing of the located feature is performed to derive a first feature descriptor using a feature descriptor extraction algorithm. The feature descriptor is stored in a memory. A database of feature descriptors having geolocation information associated with the feature descriptors is searched for a match to the first feature descriptor. The geolocation information is then made available for access.

Hardware Front-End For A Gnss Receiver

US Patent:
20190146094, May 16, 2019
Filed:
Oct 19, 2018
Appl. No.:
16/165529
Inventors:
- Sunnyvale CA, US
SHAWN D. WEISENBURGER - DENVER CO, US
International Classification:
G01S 19/36
H01Q 9/04
H01Q 1/22
H01Q 21/06
G01S 19/32
H01Q 25/02
Abstract:
A hardware front-end for a software-defined GNSS receiver, which includes an antenna connected to a transmission line that is connected to a pair of separate circuits, one for receiving L1 signals and one for receiving L2 signals. Each circuit includes at least one bandpass filter, at least one LNA, and a single-chip GNSS receiver that receives analog RF signals and provides digitized I and Q signals. The pair of circuits differ in that a first one is designed to receive, filter, and amplify RF signals at the L1 frequency corresponding to the designed input frequency of the receiver and the second one is designed to receive, filter, and amplify RF signals at the L2 frequency, which is significantly different from the first frequency. The second circuit also includes a mixer to convert the L2 frequency to the L1 frequency, so that a similar receiver can be used in each circuit.

US Patent:
20160035096, Feb 4, 2016
Filed:
Oct 13, 2015
Appl. No.:
14/882243
Inventors:
- Sunnyvale CA, US
Chad McFADDEN - Lafayette CO, US
Robert WOLD - Phoenix AZ, US
Venkateswaran KASIRAJAN - Tamil Nadu, IN
Nicholas C. TALBOT - Ashburton, AU
Peter Van Wyck LOOMIS - Sunnyvale CA, US
Shawn D. WEISENBURGER - Denver CO, US

Michael V. McCUSKER - Los Altos CA, US
International Classification:
G06T 7/00
G06K 9/52
H04N 5/44
G06F 17/30
H04N 5/232
G01B 11/26
G06T 7/60
Abstract:
A plurality of images are captured by an image capturing device that is an integral part of the mobile data collection platform from at least two different perspectives that depict a point of interest in a scene. Coincident with capture of each of the plurality of images, orientation information is obtained via orientation sensors of the mobile data collection platform, a position fix of an antenna associated with the mobile data collection platform is determined, and a position of an entrance pupil of the image capturing device is calculated. Scale information associated with at least one of the images is captured. Scene data comprises the images, the orientation information and the entrance pupil positions. A three dimensional position of the point of interest at the scene is determined based on photogrammetric image processing of the scene data.

Inventors:
- Sunnyvale CA, US
Gregory Craig WALLACE - Arvada CO, US
Shawn D. WEISENBURGER - Denver CO, US
James M. JANKY - Los Altos CA, US
International Classification:
H04B 7/22
H04B 7/185
Abstract:
A method for capturing ionospheric data is disclosed. In accordance with one embodiment, a plurality of phase-coherent signals transmitted by at least one Global Navigation Satellite System (GNSS) satellite is received via a mobile multi-frequency GNSS receiver. Respective code phase data and carrier phase data for each of said plurality of phase-coherent signals are derived using a software defined GNSS receiver operating on a processor of a first communication device of the multi-frequency GNSS receiver. Respective code phase data and carrier phase data for each of the plurality of phase-coherent signals is stored in a data storage device. The respective code phase data and carrier phase data is appended with a respective time-stamp and position fix. An ionospheric sample based upon respective code phase data and carrier phase data of said plurality of phase-coherent signals is wirelessly transmitted to a second location.

Inventors:
- Sunnyvale CA, US
Gregory Craig Wallace - Arvada CO, US
Shawn D. Weisenburger - Denver CO, US
Nicholas C. Talbot - Ashburton, AU
James M. Janky - Los Altos CA, US
International Classification:
G01S 19/43
G01S 19/05
Abstract:
A radio frequency component receives and digitizes a first plurality of L1 Global Navigation Satellite System (GNSS) signals and a second plurality of L2C GNSS signals from a plurality of GNSS satellites. A software defined GNSS receiver operating on a processor of a cellular telephone separate from the radio frequency component derives carrier phase measurements from the first plurality of L1 GNSS signals and the second plurality of L2C GNSS signals during an epoch. A wireless message from a communication device located at a base location is received conveying pseudorange and carrier measurements derived from the first plurality of L1 GNSS signals from said plurality of GNSS satellites during the epoch. The cellular telephone determines a distance from the base location to said first location.
