Air Force Postpones Boeing Delta II Launch Attempt of Global Positioning Satellite
U.S. Air Force officials scrubbed tonight's launch attempt of a Boeing [NYSE: BA]
Delta II rocket carrying a Lockheed Martin-built Global Positioning System (GPS) IIR-4 spacecraft for the U.S. Air Force.
The launch team made the decision to scrub to further investigate a technical issue with ground support equipment that provides electrical power to the spacecraft.
The next launch attempt will be tomorrow, April 22. The 29-minute launch window opens at 11:01 p.m. EDT and closes at 11:30 p.m.
Recognized as the world's premier navigation satellite system, GPS operates via a constellation of satellites, a ground control system, and thousands of terminals to help locate and guide military and civilian users in the air, in space, at sea, and on the ground. The original 24 GPS satellites and replacement satellites have been carried into orbit by Delta rockets.
