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.

Gates Backs Lynn for Key Defense Post

William J. Lynn III

(Updated Jan.26) President Barack Obama’s nomination of William J. Lynn III, a senior vice-president at Raytheon Corporation, for deputy secretary of defense and his granting Lynn a waiver from the new administration’s own rules on former lobbyists has provoked considerable criticism from some quarters.

As the number two official in the Department of Defense (DoD), Lynn would report directly to Robert Gates, the current secretary of defense who has continued in that position in the new administration, the only holdover from ex-President Bush’s cabinet. Gates has come out strongly in support of Lynn, saying that he requested the waiver from the president.

Among other responsibilities, the deputy secretary serves as the co-chair of
the Space-Based Positioning, Navigation, and Timing (PNT) Executive
Committee (ExCom). Lynn would succeed Gordon England, who has paid a lot of attention to GPS during his term in office and enhanced the role of the PNT ExCom as an arbiter and advocate for the GPS program throughout the federal government.
