GNSS Forum: How Galileo Can Help Europe Recover from the Economic Crisis

Back in 1999, the European Union decided to set up a global satellite navigation system (GNSS), known as Galileo, for civil and commercial use. Early 2010 the European Commission awarded the contracts for Galileo’s first satellites, launchers and support services. In 2011 the European system will finalize its validation phase. As a result, the initial service provision of Europe’s satellite navigation system could start as of early 2014.

Modernization Milestone

The New Year’s festivities had ended and satellite operators at the 2d Space Operations Squadron (2 SOPS) at Schriever Air Force Base, Colorado, were hard at work conducting routine operations on the GPS satellites. At around 11:30 in the morning local time (1830 UTC) on January 1, 2004, range errors for space vehicle number (SVN) 23 began to rapidly drift above the 30-meter threshold.

New Software, Delays for GPS Control Segment, IIF Satellite

The U.S. Air Force GPS Wing and the 50th Space Wing will implement a new ground system software release on January 11 to enable telemetry, tracking, and commanding for the new GPS IIF satellites and provide over-the-air distribution of encryption keys for military user P(Y)-code equipment.

The software will be implemented by the GPS Master Control Center at Schriever AFB, Colorado.

Meanwhile, the schedules for launching the first IIF spacecraft and awarding the prime contract for modernization of the GPS operational control segment (OCX) continue to slip.

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.
