Publication number: 20220334266Abstract: A method and system for using GPS signals and a magnetic field to track an underground magnetic field source. A tracker having an antenna for detecting the magnetic field and a GPS receiver is coupled to a processor. The magnetic field is used by the antenna to direct the tracker to a field null point. Once multiple measurements of the field are taken, the changes in signal strength as the absolute position of the tracker is changed, are used to determine whether the closest field null point is in front of or behind the underground beacon. The position and depth of the beacon can then be estimated.Type: ApplicationFiled: July 5, 2022Publication date: October 20, 2022Inventors: Scott B. Cole, Brian J. Schrock, Klayton Day Jones

Patent number: 9971013Abstract: A tracker used to analyze a desired borepath prior to horizontal directional drilling operations. The tracker analyzes an amount of interference present at a plurality of different frequencies at multiple locations along the borepath and maps a plot of the interference at the different frequencies. The lower the point on the plot, the less interference present at that frequency at the location analyzed. The tracker summarizes the overall interference along the desired borepath for the different frequencies analyzed and will recommend a preferred frequency. An operator may program the beacon prior to boring operations to emit a beacon signal at the preferred frequency. The operator may also tune the tracker to receive the preferred frequency. The tracker and beacon may then communicate during boring operations at the preferred frequency in order to detect the position of the beacon underground relative to the tracker.Type: GrantFiled: August 22, 2016Date of Patent: May 15, 2018Assignee: The Charles Machine Works, Inc.Inventors: Scott B.

Patent number: 9547101Abstract: A system for identifying the location of a dipole magnetic field source below ground. The system comprises a first receiver assembly and a second receiver assembly each configured to detect the dipole magnetic field in three dimensions from a transmitter and generate antenna signals indicative of the detected dipole magnetic field. The first receiver assembly detects the dipole magnetic field from the transmitter substantially simultaneously as the second receiver assembly simultaneously detects the dipole magnetic field from the transmitter. The second receiver assembly is movable relative to both the first receiver assembly and the transmitter. A processor determines the location of the transmitter below ground based on the antenna signals generated by the first and second receiver assemblies.Type: GrantFiled: December 20, 2013Date of Patent: January 17, 2017Assignee: The Charles Machine Works, Inc.Inventors: Scott Bryan Cole, Brian J.

Patent number: 9329297Abstract: A receiver and tracking system for identifying a location of a magnetic field source. In a preferred embodiment a plurality of tri-axial antennas are positioned at three distinct points on a receiver frame. Each antenna detects a magnetic field from a source and a processor is used to determine a location of the source relative to the frame using the antenna signals.

Publication number: 20140111211Abstract: A method and receiver system for identifying a location of a magnetic field source using two horizontally displaced tri-axial antennas. In a preferred embodiment two tri-axial antennas are positioned at opposite ends of a receiver frame. Each antenna detects in three dimensions a magnetic field from a source or transmitter. The receiver is maintained in a horizontal plane and the receiver is moved in the horizontal plane until a flux angle measured at each of the two points is zero so that the receiver is in the vertical plane perpendicular to the axis of the source. The depth and location of the source in three dimensions relative to the receiver is determined using the detected field values. The receiver is moved in a direction defined by a line containing the two points of the receiver until a magnitude of the magnetic field detected at each of the two points is substantially the same so that the receiver is positioned above the source.Type: ApplicationFiled: December 20, 2013Publication date: April 24, 2014Applicant: The Charles Machines Works, Inc.Inventors: Scott Bryan Cole, Brian J.
