Ready to Navigate!

After three decades of increasingly widespread use, satellite navigation-based services have changed significantly, especially for general users in the mass market. New technology enablers such as assisted GPS (A-GPS), the use of massively parallel correlation, and the application of advanced positioning techniques have significantly enhanced the time-to-first-fix (TTFF) and sensitivity of today’s receivers.

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

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.
