1. A non-contact position determination system comprising:

  • a bulldozer comprising an implement coupled therewith;

    a first system configured for determining without contact a position of said implement relative to said bulldozer and for determining a difference in incidence angle between the implement and a particular part of said bulldozer;

    said first system including an incidence angle detection component comprising;

    an emitter coupled with said implement; and

    a detector coupled with said particular part of said bulldozer and configured to receive a one-way transmission of a light that travels without changing direction from said emitter, wherein said incidence angle detection component is configured for determining said incidence angle between said implement and said particular part of said bulldozer based on said one-way transmission of said light from said emitter and for using said incidence angle to determine said position of said implement relative to said bulldozer;

    a second system configured for determining a geographic position of said bulldozer; and

    a control system configured for determining a geographic location of said implement using data from said first system and said second system.
