St Louis MO (SPX) Jul 18, 2007 Boeing 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. "GPS III will further evolve navigation and positioning capabilities," said Howard Chambers, vice president and general manager of Boeing Space and Intelligence Systems. "Boeing's GPS III solution delivers accelerated warfighter capability on time with a low-risk, high-confidence program. Our solution, which combines signal and power improvements, is the best value for the nation and will provide a more capable GPS service for both civilian and military users." Boeing is building on its successful experience of producing 43 GPS satellites to date for Block I, II, IIA and the current IIF series. That heritage ensures GPS III will be compatible with existing civil and military user equipment. Boeing's mature, flexible and scalable GPS III design allows for future capability upgrades while minimizing life cycle costs. GPS III is set to take navigation timing and accuracy to the next level. Its more powerful broadcast signals will incorporate a new civil signal making it interoperable with Europe's upcoming Galileo system, advanced anti-jamming capabilities and the military signal known as the M-code, which provides more secure operations for the warfighter. Boeing's current production of 12 GPS Block IIF satellites will begin launching in 2008, and the Architecture Evolution Plan for the GPS ground station will be fully operational in September.

Pseudo-Satellites Allow Accurate Navigation In Helsinki Harbour
Paris, France (ESA) Jul 10, 2007Pseudo-satellites, ground-based substitutes used when signals from "real" satellites are not available, can deliver accurate positioning information in places where conventional solutions fail. This was demonstrated on 27 June in Helsinki harbour as part of a project supported by ESA. For geographical or technical reasons, satellite positioning signals are not always available. Northern regions such as Finland, with their low angle"of-view to geostationary satellites and reduced GPS coverage, suffer particularly with this problem. |
