The U.S. Air Force is preparing to launch an upgraded Global Positioning Systems (GPS) satellite built by Lockheed Martin aboard a Delta II rocket scheduled on 21-Dec-2003 from Cape Canaveral, Florida. The GPS IIR-10 satellite features significant performance upgrades, including an advanced antenna panel, which will increase power for GPS receivers.
Lockheed Martin said there are eight new-generation GPS IIR spacecraft currently on orbit out of a total GPS constellation of 28 satellites. GPS IIR satellites are designed to improve global coverage and increase the overall performance of the GPS constellation. Lockheed Martin has delivered 21 of these satellites to the U.S. Air Force Space and Missile Systems Center.
