First Modernized GPS Satellite Declared Operational

The first modernized Global Positioning System (GPS) satellite has been declared fully operational by a joint U.S. Air Force-Lockheed Martin team. The satellite was launched on September 25, and has been undergoing testing since then.

The satellite is the most technologically advanced GPS satellite ever developed. Among its features:

• A modernized antenna panel that provides increased signal power to receivers on the ground.
• A second civilian signal that will provide users with an open access signal on a different frequency.
• Two new military signals for improved accuracy.
• Enhanced encryption and anti-jamming capabilities for the military.

Launch of a second modernized satellite is planned for early 2006. For more information see Lookheed Martin's press release via Yahoo News.
