SkyFix network expands


  • Anonymous


Three new SkyFix reference stations have been opened as part of the continued expansion of the Differential Global Positioning System (DGPS) network.

The SkyFix reference stations feed GPS data to a Radcal control center, where it is then uplinked with other reference data to the four INMARSAT ocean region communications satellites. The SkyFix correction signals, with those from the navigation satellites by the vessel's GPS unit, enable its precise position to be calculated by the onboard computer.
