1. A system for measurement of spatial coordinates comprising a probing tool and a main measuring unit (18), wherein said probing tool comprises a) a reflective object element (26), b) observation mechanism (24) located in a known position and orientation relative to said reflective object element (26) and capable of observing targets (36, 36

  • ); and

    wherein said main measuring unit comprises c) a distance measuring device (10) capable of measuring a distance from said device (10) to said reflective object element (26);

    d) a mechanism (14) constructed and adapted to direct a measuring beam from said distance measuring device (10) to said reflective object element (26);

    e) a direction determining mechanism (16) constructed and adapted to determine a direction of a measuring beam;

    f) at least two targets (36, 36

    ) located in known positions relative to said distance measuring device (10), whereby the orientation of said reflective object element (26) can be determined from observations of said targets (36, 36

    ) by said observation mechanism (24);
