Claim 4:
5. 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 generated data associated with the two or more signal components of the first predefined frequency suite or the generated data associated with the second two or more signal components of the second predefined frequency comprises separate positional information of the buried utility relative to the locator determined based on ones of the first or the second two or more signal components.
