摘要：
A tracking receiver system (20) is used to track the progress of a downhole tool (10) along a subsurface path having a desired grade. The tracking receiver system is adapted to detect a reference line (22) originating from a reference line receiver (96) and to determine the position of the downhole tool (10) along a desired subsurface path relative to the reference line. In an alternative embodiment the tracking receiver system (20) may comprise a global positioning satellite system to provide information used to determine the position of the downhole tool relative to the desired subsurface path.
