1. A boundary tracking system for a work site, comprising:
- a plurality of signal transmitting devices configured to be positioned at underground locations and to originate signals to be transmitted from the underground locations to aboveground having frequencies ranging from about 900 MHz to about 2.4 GHz, wherein the plurality of signal transmitting devices are configured to be activated by a query signal;
a receiving device configured to be located aboveground and to receive the signals having frequencies ranging from about 900 MHz to about 2.4 GHz that originate from the plurality of signal transmitting devices and to generate an output based on the received signals; and
a controller configured to determine the underground locations of the plurality of signal transmitting devices based on the output from the receiving device.

Abstract
The boundary tracking system has a plurality of signal transmitting devices located to represent at least one boundary of a work site. The boundary tracking system also has a receiving device configured to receive signals transmitted from one or more of the plurality of transmitting devices and to generate an output based on the received signals. The boundary tracking system also has a controller configured to determine a location of at least one of the plurality of transmitting devices based on the output from the receiving device.
