The U.S. Coast Guard and its parent agency, the Department of Homeland Security, announced earlier this month that loran-C stations in the U.S. will be progressively shut down between next month and October. The U.S. considers maintaining its loran station network, costing $36 million per year, unaffordable.
Come fall, the U.S. Congress will decide the fate of loran and its successor eLoran when members of the Congressional House and Senate Appropriations Committees meet in conference to determine which of their respective favored projects will live on and which will not.
Under a Department of Homeland Security appropriations bill for fiscal year 2010 that was passed by the House last week, lawmakers lauded the Transportation Security Administration (TSA) for working with general aviation stakeholders to develop a modified Large Aircraft Security Program (LASP) rule that “minimizes adverse affects on general aviation while addressing security concerns.” H.R.2892 urges the TSA to “weigh all the costs and benefit

The hearings were held to solicit user comments on those policies before publication of this year’s federal radionavigation plan (FRP), which will be available by year-end.
To counter the possibility of jammed and “spoofed” signals, the authors of a U.S. Department of Transportation report on GPS vulnerability released on September 10 recommend that GPS not be relied upon as the sole source in critical applications, including precision approaches.
Three senators have written Transportation Secretary Norman Mineta in support of continuing the loran-C navigation system, as recently announced by the DOT, saying the move was long overdue.
Other than the occasional contradiction, the recently released federal radionavigation plan (FRP) reveals few surprises. The FRP does, however, include a revised schedule
