      Global Positioning System IIF in factory

      Global Positioning System

      Boeing’s Global Positioning System IIF enables customers to know and track where they are anywhere on the globe via a satellite link.

      Precision location, timing

      The Global Positioning System IIF is a current iteration of the GPS satellite, which Boeing began building in 1978. The company has constructed more than 40 GPS satellites that cumulatively have provided more than 540 years of on-orbit service. GPS satellites orbit some 12,000 miles above the Earth and comprise a worldwide timing and navigation system.

      Milestones
