DARPA Network Challenge Abandons GPS for the Power of Social Networking

(Updated December 7, 2009) A Massachusetts Institute of Technology team won the DARPA Network Challenge on Saturday, December 5. They took home a $40,000 cash prize from the Defense Advanced Research Projects Agency.

The team successfully located 10 eight-foot diameter, bright red weather balloons moored in plain site at locations across the United States.

Apparently, the DARPA personnel in charge were sensitive to frigid winter weather in the heartland -  most of the balloons turned out to be moored in pleasant places for an outdoor December search: Portland, Oregon; San Francisco and Santa Barbara, California; Scottsdale, Arizona; Katy, Texas; Memphis, Tennessee; Atlanta, Georgia; Miami, Florida; Charlottesville, Virginia; and Christiana, Delaware.

U.S. Air Force Plans to Improve GPS Constellation Geometry for Military Forces in Afghanistan

U.S. Air Force officials are moving to reconfigure the GPS constellation to create a 27-satellite geometry that will improve the availability and accuracy of positioning, navigation, and timing (PNT) capabilities for U.S. military forces in Afghanistan and Iraq.

Although the constellation currently has 30 operational space vehicles (SVs), not including the SVN49/PRN1 that has still not been set healthy, a number of the spacecraft are located nearby other satellites — effectively creating a 24-SV geometry. (See accompanying figure.)
