Other than the occasional contradiction, the recently released federal radionavigation plan (FRP) reveals few surprises. The FRP does, however, include a revised schedule
for the gradual phaseout of certain VOR, VOR/DME and ILS installations across the continental U.S., primarily following nationwide certification of WAAS. Originally planned to commence in 2008, the phaseout has now slipped to 2011.

Navstar, the official U.S. Air Force program moniker for the constellation of satellites most of us refer to simply as GPS, has undergone a multitude of technical changes and upgrades in the nearly 30 years since a group of military and civil engineers first sat down in the Pentagon to talk about the far-reaching precision navigation concept.

March 3 is the final date by which the user community can file its comments on the FAA’s Oct. 1, 2007, Notice of Proposed Rulemaking (NPRM) regarding the agency’s $2+ billion transition plan to the Automatic Dependent Surveillance-Broadcast (ADS-B) system.

Just when many thought loran was dead, it is coming back, albeit in a different guise. The President’s recently released FY2009 budget includes funding for the Coast Guard to continue operating the current loran network in readiness for its upgrade in 2009 to enhanced loran (eLoran).

Loran will continue, and be modernized, according to the recently released U.S. Fiscal Year 2009 budget. Furthermore, system responsibility will be placed with the National Protection and Programs Directorate of the Department of Homeland Security, which has chosen it as the backup for national infrastructure elements that currently depend on GPS.
