The float and gun array surface navigation positioning was provided by the Buoylink rGPS system. The in-sea units incorporated a GPS receiver and interfacing for direct data transmission of the raw satellite pseudo-range data transmitted either by wired telemetry or by UHF radio.

On board the vessel, the raw pseudo range data and phase measurement from each remote unit is matched with simultaneously received data at the vessel’s GPS receiver to compute a vector describing the location of the float unit relative to the vessel.
