Abstract

A buried object locator which may include at least one antenna array including three orthogonal antennas, each antenna sharing a common center point, is disclosed. An electronic circuit may be connected to the array and used to determine location information of the buried objects by measuring signal strength and magnetic field angular data in three dimensions.

Claims

exact text as granted — not AI-modified
We claim: 
     
         1 . A buried utility locator, comprising:
 a plurality of magnetic field antenna arrays, each array including three orthogonally oriented antenna elements; and   an electronic circuit operatively coupled to the magnetic field antenna arrays for determining information about a buried utility based on magnetic field signals emitted therefrom.
