The U.S. Air Force is preparing to launch the first modernized Global
Positioning System (GPS) satellite built by Lockheed Martin [NYSE: LMT]
aboard a Delta II rocket on Sept. 25, from Cape Canaveral Air Force Station,
Fla. The satellite is the most technologically advanced GPS satellite ever
developed and will provide significantly improved navigation performance for
U.S. military and civilian users worldwide.

The satellite, designated GPS IIR-14 (M), is the first in a series of eight
GPS IIR satellites that Lockheed Martin is modernizing for its customer at
the Navstar GPS Joint Program Office, Space and Missile Systems Center, Los
Angeles Air Force Base, Calif.

The modernized series will offer a variety of enhanced features for GPS
users, such as a modernized antenna panel that provides increased signal
power to receivers on the ground, two new military signals for improved
accuracy, enhanced encryption and anti-jamming capabilities for the
military, and a second civil signal that will provide civil users with an
open access signal on a different frequency.

The current GPS constellation of 28 spacecraft includes 12 fully operational
Block IIR satellites, which were developed to improve global coverage and
increase the overall performance of the global positioning system.

The Global Positioning System enables properly equipped users to determine
precise time and velocity and worldwide latitude, longitude and altitude to
within a few meters. Air Force Space Command's 2nd Space Operations
Squadron (2SOPS), based at Schriever Air Force Base, Colo., manages and
operates the GPS constellation for both civil and military users. GPS IIR-M
production occurs at Lockheed Martin facilities in Valley Forge, Pa. The
modernized navigation payload is provided by ITT Industries in Clifton, N.J

Boeing Delta II Delivers First Modernized GPS Satellite to Orbit



ST. LOUIS, Sept. 26, 2005 — A Boeing [NYSE: BA] Delta II launch vehicle today successfully delivered the first of the modernized Block IIR Global Positioning System (GPS) satellites to space for the U.S. Air Force.



The Delta II rocket carrying the GPS IIR-14 (M) spacecraft lifted off from Space Launch Complex 17A at Cape Canaveral Air Force Station, Fla., yesterday at 11:37 p.m. EDT. Following a nominal 24-minute flight, the rocket deployed the satellite to a transfer orbit.



The Boeing Delta II 7925-9.5 configuration vehicle used for this mission featured a Boeing first stage booster powered by a Pratt & Whitney Rocketdyne RS-27A main engine and nine Alliant Techsystems (ATK) solid rocket boosters. An Aerojet AJ10-118K engine powered the storable propellant restartable second stage. A Thiokol Star-48B solid rocket motor propelled the third stage prior to spacecraft deployment. The rocket also flew with a nine-and-a-half-foot diameter Boeing payload fairing.



A redundant inertial flight control assembly built by L3 Communications Space & Navigation provided guidance and control for the rocket that enabled a precise deployment of the satellite.



The GPS IIR-14 (M) mission also marked the 100th flight of the Delta II using the ATK 40-inch diameter version solid rocket motors.



Boeing provides launches for the GPS program aboard Delta II vehicles and has a planned GPS manifest through at least 2007.



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 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 new GPS IIR-14 (M) is the first of the modernized GPS satellites that incorporates various improvements to provide greater accuracy, increased resistance to interference and enhanced performance for users.
