Boeing Delta II Adds Another GPS Satellite to Air Force Constellation

ST. LOUIS, Nov. 06, 2004 -- A Boeing [NYSE: BA] Delta II rocket successfully deployed a Global Positioning System (GPS) satellite to orbit today for the U.S. Air Force, marking the 61st consecutive successful mission flown aboard the Delta II.

The rocket carrying the GPS IIR-13 spacecraft lifted off at 12:39 a.m. EST from Space Launch Complex 17B, Cape Canaveral Air Force Station, Fla. The spacecraft was injected to a transfer orbit following a 26-minute flight.

"Our Delta team achieved 100-percent mission success this year for the GPS program, supporting three missions," said Dan Collins, vice president, Boeing Expendable Launch Systems. "We look forward to next year as we continue our role in supporting this vital program utilizing the Delta II launch vehicle."

The Boeing Delta II 7925-9.5 configuration vehicle used for today's mission featured a Boeing Rocketdyne RS-27A main engine, nine Alliant Techsystems solid rocket boosters, an Aerojet AJ10-118K second-stage engine, a Thiokol Star 48B third-stage engine, and a nine-and-a-half-foot diameter Boeing payload fairing.

Boeing is the current sole launch service provider for the GPS program and has a backlog of GPS missions planned aboard Delta II vehicles through at least 2008.

The GPS network supports U.S. military operations conducted from aircraft, ships, land vehicles and by ground personnel. Additional use includes mapping, aerial refueling and rendezvous, geodetic surveys, and search and rescue operations.

GPS provides military and civilian users three-dimensional position location data in longitude, latitude and elevation as well as precise time and velocity.

The GPS constellation is operated as a 24-satellite system consisting of six planes with a minimum of four satellites per plane.

GPS satellites orbit the earth every 12 hours, emitting continuous navigation signals. The signals are so accurate, time can be figured to within one millionth of a second, velocity within a fraction of a mile-per-second, and location to within 100 feet.

The next Delta launch is NASA's SWIFT mission aboard a Delta II scheduled for November 17 from the Cape.
