1. A method for navigating a first object with reference to a second object, comprising:

  • obtaining a set of carrier-phase measurements according to signals received at the first object from a plurality of satellites;

    correcting the set of carrier-phase measurements using corrections computed for the second object according to signals received at the second object from the plurality of satellites;

    wherein the second object is a moving object;

    determining a position correction for the first object using the corrected set of carrier-phase measurements;

    receiving a computed position of the second object; and

    computing a vector difference between a computed position of the first object and the computed position of the second object.
