1. A system for tracking the position of an instrument relative to an area of interest, comprising:

  • a first fixator secured to a first point along said area of interest, said first fixator being configured to carry first and second localizing devices;

    a second fixator secured to a second point along said area of interest, said second fixator being configured to carry said first localizing device; and

    a third localizing device positioned proximate a third point along said area of interest, said second point being located proximate said first and third points, said third localizing device communicating with said first localizing device at said second fixator and said second localizing device at said first fixator communicating with said first localizing device at said second fixator such that the position of said second localizing device at said first fixator can be determined relative to the position of said third localizing device proximate said third point, said second localizing device at said first fixator being attachable to said instrument and said first localizing device at said second fixator being attachable to said first fixator such that said first localizing device on said first fixator communicates with said second localizing device on said instrument in order that the position of said second localizing device on said instrument can be determined relative to said first localizing device on said first fixator and to said third localizing device proximate said third point.
