Ship derives its precise position using GPS
Inertial navigation sensors provide Ships motion for glide‐slope solution
Ship broadcasts ship position and glide‐slope solution via encrypted UHF data link
Aircraft derives its precise position using GPS
Aircraft receives glide‐slope data and reports back position via two‐way data link
Software algorithms calculate corrections and drive aircraft displays to maintain glide‐slope, may be coupled to flight controls Differential GPS gives relative position with high accuracy and integrity ]
