Abstract: A buried object locator which may include at least one antenna array including three mutually orthogonal antennas each sharing a common center point senses electromagnetic signals emitted by two or more buried objects such as utility lines, pipes or sondes. A circuit at least partially mounted in a housing of the locator may be connected to the array and used to determine location information of the buried objects by measuring signal strength and field angles in three dimensions.

Abstract: Antenna systems for receiving right and left hand circularly polarized signals are disclosed. An antenna system embodiment includes a top printed circuit board (PCB), a ground plane, and an antenna array including four conductive antenna elements positioned at relative zero, 90, 180, and 270 degree increments radially about a shared center point on the PCB, with each antenna element sloping upward in a left-handed direction from the ground plane towards the top PCB and connected to the ground plane and top PCB.

Abstract: Systems and methods for electronically marking, locating, and virtually displaying buried utilities are disclosed. According to one embodiment, one or more electronic marker devices may be placed below a ground surface in proximity to a buried utility, and marker device data indicative of position and/or identity of such electronic marker devices may be obtained. The obtained marker device data may be associated to the utility data and stored in a database. The stored data may thereafter be retrieved based in part on the marker device data for use in subsequent locate operations and/or for other purposes.
