GAO Report on GPS Satellite Constellation Status: The Pushback

Two weeks after a Government Accountability Office (GAO) report warned of potential gaps in the GPS satellite constellation, reassurances from Department of Defense (DoD), U.S. Air Force, GPS program officials, and industry are slowly restoring calm to an anxious public.

Coupled with a May 7 congressional hearing (and subsequent media coverage) that fanned the flames, the report described scenarios — for instance a two-year setback in launching the first GPS III spacecraft — that could lead to deterioration in the quality of GPS service due to delays in building new generations of satellites and past program management problems. The news coverage drew primarily on the GAO report and prepared statements presented at the hearing and not on the much more interesting dialog with subcommittee members captured on video or on the assumptions and methodology underlying the constellation analysis.

First Look: Initial Observations of the GPS L5 Broadcast and L1 Signal Anomaly

(Updated May 22, 2009) Leading researchers from Ohio University, Stanford, and the University of Colorado have released their initial observations of the GPS L5 signal broadcast, including an anomaly in SVN49’s L1 signal reported by the GPS Wing’s chief engineer on May 4.

The U.S. Air Force switched on the eagerly awaited, modernized L5 signal on April 10 after the successful launch of the newest GPS Block IIR-M satellite – SVN49 – in March. This was the first broadcast of a GPS signal in a frequency band dedicated solely for civilian use.
