System and method for detecting and locating underground objects
First Claim
1. A system for detecting and locating an underground object comprising:
- a plurality of stationary transmitter receivers operating in a radio frequency, said plurality of stationary transmitter receivers defining a coordinate system for an area of interest;
a sensor adapted to detect an underground object and to provide a presence data upon detection of said underground object; and
a mobile transmitter receiver operating in a radio frequency, said mobile transmitter receiver being movable with said sensor, and adapted to, at least one of receive and transmit location data indicative of location of said mobile transmitter receiver in said coordinate system.

Abstract
A system for detecting and locating an underground object having stationary RF transmitter receivers that define a coordinate system for an area of interest, a sensor adapted to detect presence of an underground object and to provide a presence data, and a mobile RF transmitter receiver that is movable with the sensor, and is adapted to receive and/or transmit location data indicative of location of the mobile transmitter receiver in the coordinate system. A method is also provided for detecting and locating underground object including the steps of establishing a coordinate system for an area of interest, detecting presence of an underground object and providing a presence data upon detection of the underground object, and transmitting and/or receiving location data in a radio frequency, the location data being indicative of location of the underground object in the established coordinate system.
