Worth Watching: Update to GPS

We may want to talk, at some point in Annapolis, about the announcement by Commerce of an upgrade to US GPS capabilities. From a Commerce Press Release, linked from Adena Schutzberg's blog:

U.S. Commerce Deputy Secretary David Sampson will keynote the U.S. Chamber of Commerce's public media forum on Next-Generation GPS for Enhanced Business Productivity: "Because Time Is Money, and Location is Everything!" Wednesday, January 25.

Sampson will announce the availability of new, next-generation Global Positioning System (GPS) capabilities, including a second civilian GPS signal enabling significant improvements in accuracy and reliability.
