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.

New Software, Delays for GPS Control Segment, IIF Satellite

Block 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.
