Three GPS Satellites Moved Into New Positions for More Robust, Accurate Signals

Three GPS Satellites Moved Into New Positions for More Robust, Accurate Signals

(Update June 15, 2011 Inside GNSS) Completion of Satellite Repositioing Optimizes GPS Constellation

By next June, the United States GPS constellation will attain the most optimal geometry in its nearly 33-year history. Over time, that means a more robust signal, more accuracy and more reliability in GPS-challenged environments.

The 50th Space Wing is in the middle of maneuvering six GPS satellites into more favorable positions. The two-phase operation, called "Expandable-24"  is halfway to completion.

GPS Programs Push Ahead

The GPS program continues progress on several fronts — in space and on the ground.

During fall 2010, the U.S. Air Force and the Raytheon Company team developing the GPS Advanced Control Segment (OCX) successfully carried out an integrated baseline review (IBR) for the next-generation system on schedule.

When completed in 2015 under the current schedule, GPS OCX will deliver control segment enhancements designed to provide secure, accurate and reliable navigation and timing information to military, commercial and civil users.
