First Lockheed Martin-Built GPS Satellite Marks 10 Years In Service
King Of Prussia PA (SPX) Jul 25, 2007 The first U.S. Air Force Global Positioning System Block IIR (GPS IIR) satellite, built by a team led by Lockheed Martin, has surpassed its 10-year design life of on-orbit service, providing the U.S. military and civil users world-wide with highly accurate navigation capabilities since 1997. Launched from Cape Canaveral on July 23, 1997, the first GPS IIR satellite is one of 30 operational GPS satellites currently on orbit. Based on the navigation user range error, which measures GPS accuracy, the Block IIR satellites enable properly equipped users to determine precise time and velocity, and worldwide latitude, longitude and altitude to within one meter. Lockheed Martin Space Systems, Valley Forge, Pa., is the prime contractor for the GPS IIR program. The company designed and built 21 IIR spacecraft for the Global Positioning Systems Wing, Space and Missile Systems Center, Los Angeles Air Force Base, Calif. The final eight spacecraft, designated Block IIR-M, were modernized to enhance operations and navigation signal performance for military and civilian GPS users around the globe. ITT, Clifton, N.J. supplied all 21 navigation payloads for both the IIR and IIR-M spacecraft. "The improved performance of the GPS constellation is due in large part to the success of the Block IIR and IIR-M spacecraft series and a joint industry-government team dedicated to operational excellence and mission success," said Don DeGryse, Lockheed Martin's vice president of Navigation Systems. "We are proud to provide our customer with high-quality, high-value satellites that will continue to provide GPS users around the globe with enhanced navigation service for many years to come." The GPS constellation provides critical situational awareness and precision weapon guidance for the military. The worldwide system also supports a wide range of civil, scientific and commercial functions - from air traffic control to the Internet - with precision location and timing information. The current fleet of Block IIR and IIR-M satellites within the overall GPS constellation has reached over 67 cumulative operational years on orbit. The company is leveraging its proven record of building advanced global positioning system satellites for the next-generation system, known as GPS III. The Lockheed-led GPS III Space Segment team, which includes ITT and General Dynamics, is currently working under a Phase A Concept Development contract, with the Air Force expected to award a multi-billion dollar development contract to a single contractor in late 2007.

Boeing To Submit Proposal For Global Positioning System 3
St Louis MO (SPX) Jul 18, 2007Boeing is preparing a response to a U.S. Air Force Request for Proposals for the development and production of an enhanced constellation of Global Positioning System satellites known as GPS III. The proposal is due Aug. 27, and the potential $1.8 billion contract award for the first eight Block A GPS III satellites along with an option for four more, is anticipated by the end of 2007 to meet a projected 2013 launch. |
