1. A method for determining the location of a location determination (LD) station, the method comprising the steps of:

  • receiving LD signals from a plurality of LD signal sources at an LD station and determining a pseudorange value between the LD station and each LD signal source, where the number of LD signal sources is less than the number of location fix coordinates for the LD station to be determined;

    processing the pseudorange values to produce at least one exact linear relation relating at least first and second location fix coordinates for the LD station without iteration; and

    using the at least one linear relation together with at least one pseudorange value to obtain at least one exact non-linear relation relating the at least first and second location fix coordinates without iteration.
