Method And Apparatus For Determining Vehicle Position Using A Satellite Based Navigation System

US Patent:
5359521, Oct 25, 1994
Filed:
Dec 1, 1992
Appl. No.:
7/983697
Inventors:
Christos T. Kyrtsos - Peoria IL
Adam J. Gudat - Edelstein IL
Douglas W. Friedrich - Pekin IL
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
G01S 502
H04B 7185
US Classification:
364449
Abstract:
An apparatus and method for determining the position of a vehicle relative to the center of the Earth uses navigation signals from a satellite based navigation system which includes a plurality of satellites orbiting the Earth. In one embodiment, a plurality of antennas are mounted on the vehicle. The distance between the antennas is precisely known. This distance is used to constrain the solution of a vehicle position estimate to improve the accuracy of the position estimate. In another embodiment, a plurality of receiver systems are used in place of the plurality of antennas. In yet another embodiment, a plurality of base stations with known positions are used to constrain the solution of the vehicle position estimate.

System And Method For Using Parabolic Models To Improve Position Estimates From A Global Positioning System

US Patent:
5629855, May 13, 1997
Filed:
Jun 1, 1995
Appl. No.:
8/457960
Inventors:
Christos T. Kyrtsos - Peoria IL
James W. Sennott - Bloomington IL
Adam J. Gudat - Edelstein IL
Dana A. Christensen - Peoria IL
Douglas W. Friedrich - Pekin IL
Darrell E. Stafford - Dunlap IL
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
G01C 2100
US Classification:
364460
Abstract:
Systems and methods allow for the accurate determination of the terrestrial position of an autonomous vehicle in real time. A first position estimate of the vehicle 102 is derived from satellites of a global positioning system and/or a pseudolite(s). The pseudolite(s) may be used exclusively when the satellites are not in the view of the vehicle. A second position estimate is derived from an inertial reference unit and/or a vehicle odometer. The first and second position estimates are combined and filtered using novel techniques to derive a more accurate third position estimate of the vehicle's position. Accordingly, accurate autonomous navigation of the vehicle can be effectuated using the third position estimate.

Antenna Mounting Apparatus

US Patent:
5410325, Apr 25, 1995
Filed:
Aug 9, 1993
Appl. No.:
8/103369
Inventors:
Douglas W. Friedrich - Pekin IL
Carl A. Kemner - Peoria Heights IL
N. Keith Lay - Peoria IL
Joel L. Peterson - East Peoria IL
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
H01Q 132
US Classification:
343713
Abstract:
An apparatus for mounting an antenna assembly to an elevationally movable portion of a vehicle dump bed includes a mountable support member having first and second end portions. The first end portion is fixed to the vehicle bed. The antenna assembly has an active element connected to a first end of a mounting element and a counterweight element connected to a second end of a mounting element. An intermediate portion of the mounting element is connected to the second end portion of the mountable support member. The antenna assembly is therefore free to rotate about at least one axis parallel to the axis of rotation of the elevationally movable dump bed.

System And Method For Providing Accurate Vehicle Positioning Using Spatial Bias Techniques

US Patent:
5555503, Sep 10, 1996
Filed:
Nov 23, 1993
Appl. No.:
8/155374
Inventors:
Christos T. Kyrtsos - Peoria IL
Adam J. Gudat - Edelstein IL
Dana A. Christensen - Peoria IL
Douglas W. Friedrich - Pekin IL
Darrell E. Stafford - Dunlap IL
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
G06F16500
US Classification:
364449
Abstract:
A vehicle position determination system and method provide accurate vehicle positioning using a global positioning system. Spatial bias techniques are used to improve positioning accuracy while the vehicle is in the midst of a relatively linear path and is not approaching a drastically nonlinear path. The use of spatial bias techniques is suspended while the vehicle is approaching or in a drastically nonlinear path.
