Michael Casteel, U.S. ArmyU.S. Air Force officials are moving to reconfigure the GPS constellation to create a 27-satellite geometry that will improve the availability and accuracy of positioning, navigation, and timing (PNT) capabilities for U.S. military forces in Afghanistan and Iraq.
Although the constellation currently has 30 operational space vehicles (SVs), not including the SVN49/PRN1 that has still not been set healthy, a number of the spacecraft are located nearby other satellites — effectively creating a 24-SV geometry. (See accompanying figure.)
