1. A tracking system comprising:

  • an inertial sensor for producing velocity data in response to its movement;

    a computer in wireless communication with the inertial sensor and programmed to translate the velocity data into location data indicative of a location of the inertial sensor;

    an underground reset station at which the inertial sensor is positionable for resetting alignment of the inertial sensor to a home position; and

    a pair of underground geodetic survey monuments to facilitate alignment of the inertial sensor to the home position.
