Abstract:
1. A system for determining the dimensional coordinates of a point of interest in a work space, comprising: a plurality of fixed position ranging radios located at known positions in the work space, a wand having a first end configured for indicating a point of interest, a pair of ranging radios mounted on said wand, a first ranging radio spaced from said first end by a first distance, and a second ranging radio spaced from said first ranging radio by a second distance, said first and second distances being substantially equal, and a measurement circuit, responsive to said pair of ranging radios, for determining the position of each of said pair of ranging radios with respect to said plurality of fixed position ranging radios, and for determining the position of said first end of said wand with respect to said plurality of fixed position ranging radios.
