President’s 2009 Budget Proposal Directs DHS to Implement eLORAN

Antiquated LORAN vacuum tube

The Bush administration appears to have finally made a long-delayed decision to complete implementation of an enhanced LORAN (LOng RAnge Navigation) system to serve, in part, as a back-up to GPS.

Late in the drafting process of the Fiscal Year 2009 (FY09) budget proposal that went to Congress earlier this week (February 4), officials added language “migrating” the LORAN-C system from the U.S. Coast Guard (USCG) to the Department of Homeland Security’s National Protection and Programs Directorate (NPPD).

this expansion also benefits the U.S. WAAS users within the U.S., formerly on the fringes of WAAS coverage, are now well within its coverage boundaries.

Trimble Snares USCG DGPS Contract; NDGPS Imperiled

Even as the fate of the inland portions of the Nationwide Differential GPS (NDGPS) reference network hangs in the balance, the U.S. Coast Guard (USCG) has awarded a contract to Trimble for up to 400 high-accuracy GPS reference receivers.

The Trimble NetRS reference receivers will be installed over the next three years as part of the coast guard’s modernization of the Maritime DGPS Service, which is not part of the NDGPS elements that being considered for termination.
