Abstract: A method for locating buried utilities in a utility locator is disclosed. The method may include receiving, at an antenna array for receiving magnetic field signals, a plurality of magnetic field signals at predefined signal frequencies in a predefined frequency suite, generating, in a receiver coupled to an output of the antenna array, a first receiver output signal, generating, in a processing element coupled to the receiver, a first set of data associated with the two or more signal components, and storing, in a non-transitory memory of the locator, the first set of data.

Abstract: Magnetic locators and uses of such locators for detection of buried utilities are disclosed. Outputs provided from two or more three three-axis magnetic sensors based on magnetic field signals sensed at single points in space in three axes may be used to determine information about the buried utilities including position and/or depth of the buried utilities relative to the locator.

Abstract: Systems for locating hidden utilities including a portable locator and associated portable transmitter are disclosed. The portable locator may include a magnetic field measurement module for determining a current signal in the hidden utility based on a received magnetic field, and a receiver module for receiving data from the portable transmitter. The portable transmitter may include a data transmitter module for wirelessly sending information associated with a current signal provided to the hidden utility to the portable receiver module. The portable receiver may be configured to measure a relative change in magnetic field angles, and determine an amount of cross coupling to adjacent utilities based at least in part on the measured magnetic field angles.

Abstract: Multi-frequency buried object location system transmitters and locators are disclosed. A transmitter may generate and provide output signals to a buried object at a plurality of frequencies, which may be selected based on a connection type. Corresponding locators may simultaneously receive a plurality of magnetic field signals emitted from the buried object and generate visual and/or audible output information based at least in part on the plurality of received magnetic field signals. The visual and/or audible output may be further based on signals received from a quad-gradient antenna array.
