Lockheed Martin Upgrades Legacy Global Positioning System

Lockheed Martin has upgraded the software processing and modeling for the U.S. Air Force's legacy Global Positioning System (GPS).



The recently completed update, named the Legacy Accuracy Improvement Initiative (L-AII), doubles the amount of navigation data collected and provided to Air Force operators, enhancing the Air Force's ability to monitor GPS satellites and improve system accuracy 10-15 percent for users worldwide.



Lockheed Martin is also the prime contractor for the GPS IIR program and is under contract to modernize eight GPS IIR satellites which will provide significantly improved navigation performance for U.S. military and civilian users worldwide. The first modernized GPS IIR satellite was launched successfully in September 2005 and became operational in December 2005.
