Claim 2:
3. A method for locating buried utilities in a locator, comprising:
receiving, at a locator antenna array for receiving magnetic field signals radiated from a buried utility as a result of a current flowing therein, a first plurality of magnetic field signals at first predefined signal frequencies in a first predefined frequency suite;
generating, in a receiver coupled to an output of the antenna array, a first receiver output signal including amplitude and/or phase information of a first two or more signal components in two or more simultaneously received signals of the first predefined frequency suite;
generating, in a processing element coupled to the receiver, a first set of data associated with the two or more signal components of the first frequency suite;
storing, in a non-transitory memory of the locator, the first set of data;
receiving, at the antenna array for receiving magnetic field signals from a buried utility in two or more orthogonal directions, a second plurality of magnetic field signals at second predefined signal frequencies in a second predefined frequency suite;
generating, in the receiver coupled to an output of the antenna array, a second receiver output signal including amplitude and/or phase information of second two or more signal components in two or more simultaneously received signals of the second predefined frequency suite;
generating, in a processing element coupled to the receiver, a second set of data associated with the two or more signal components of the second predefined frequency suite; and
storing, a non-transitory memory of the locator, the second set of data;
wherein the second frequency suite comprises a signal component at a passive frequency and a signal component at an active frequency, and the second set of data is based on the passive frequency signal component and the active frequency signal component.
