1. A portable metroprobe usable in performing dimensional metrology of an object using a plurality of survey points on the object, comprising:

  • an Inertial Measurement Unit (IMU) operable to determine an attitude measurement of said IMU and define a coordinate system in said IMU having an origin based on said attitude measurement of said IMU;

    an elongate probe attached to said IMU;

    a probe tip attached to said probe having a first offset length from said origin of said coordinate system in said IMU; and

    said metroprobe being operable to correlate a position of said probe tip based on said attitude measurement of said IMU and being transportable to the plurality of survey points on the object for measuring corresponding coordinates thereof based on said measured attitude of said IMU.
