1. A method of determining the unknown position of each of a plurality of points in space relative to the others of said plurality of points comprising the following elements:

  • Element 1. Establishing a wave station at each of said plurality of points in space;

    Element 2. Providing a moving means for travel in continuously unknown motion relative to said unknown positions moving along a continuously unknown path with a continuously unknown velocity;

    Element 3. Transmitting waves in the spaces between said wave stations and said means for travel;

    Element 4. Using doppler measuring means generating the physical representations of quantities linearly dependent upon the variations of the simultaneously existing unknown and unmeasured distances between said wave stations and said means for travel;

    Element 5. Feeding said physical representations into computing means;

    Element 6. Using only said physical representations generated in Element 4 computing in said computing means the otherwise unknown position of each of said plurality of points in space relative to the others of said plurality of points in space.
