1. A gyroscopic system for translating parallel and non-parallel lines between a reference line and a device to be aligned with respect to the reference line, comprising:

  • a first inertial sensor configured to be substantially stationary, said first inertial sensor comprising a first three-axis gyroscopic sensor configured to produce an output signal and a reflector;

    a second inertial sensor configured to be portable so as to be positionable adjacent to said first inertial sensor and comprising a gimbal restricted to two physical axes, a gimbal drive system, an electromagnetic energy beam generator, a second three-axis gyroscopic sensor configured to generate an output signal, and a collimator, said collimator being operable to determine an angle between a beam projected by said beam generator and a beam reflected from said reflector and to generate an output signal indicative of said determined angle; and

    a control circuit operable to process output signals generated by said collimator and said first and second three-axis gyroscopic sensors, to provide steering commands to the gimbal drive system to move the gimbal about its two physical axes such that the reflector and beam have a fixed orientation to perform calculations to compensate for a third physical axis, and determine relative orientations of said first and second inertial sensors with respect to each other.
