1. A method for determining position using carrier suppressed radio signals broadcast from a plurality of earth orbiting satellites, said method comprising:

  • a. positioning an upward looking omni-directional antenna at a survey mark;

    b. measuring the carrier phases implicit in the signals concurrently received from a plurality of the satellites independently of externally derived knowledge of the information content of the modulation thereof by cross-correlating spectral portions of such concurrently received signals, and thenc. processing the measurements to determine position information.
