1. A navigation system for determining position of an array of receiver antennas, said navigation system comprising:

  • a plurality of GNSS receiver antennas, wherein at leasta first GNSS receiver antenna of said plurality of GNSS receiver antennas has mutually complementary frequency capability with respect to a second GNSS receiver antenna of said plurality of GNSS receiver antennas;

    wherein, the first GNSS receiver antenna is separated from the second GNSS antenna by a physical spacing of at least 0.1 cycles of a highest frequency wavelength operable with the plurality of GNSS receiver antennas; and

    wherein, phases from the first and second GNSS receiver antennas are projected to a common physical point based on a relative position between the first and second GNSS receiver antennas.
