New Fiscal Year Begins with Unfinished GPS Business

New Fiscal Year Begins with Unfinished GPS Business

Most folks look to a new year as an opportunity for fresh starts and new projects. For the GPS community, however, the October 1 start of the 2016 federal fiscal year (FY16) will likely be more about the hangover — that is, the issues that are hanging over into the next 12 months, unresolved.

At the top of that list of unfinished business are two system decisions: a go/no-go determination on whether the United States will build eLoran as the U.S. backup to GPS and deciding whether or not to choose a new contractor for the GPS III program.

LightSquared Launches New GPS Receiver Tests

LightSquared’s proposed GPS receiver tests are relying on an outdated standard of GPS accuracy, a choice some experts suggest is a maneuver aimed at dramatically lowering the bar the would-be wireless broadband company has to meet for showing noninterference to GPS signals.

Ultra-wideband Re-emerges as a GNSS Interference Issue

The Federal Communications Commission (FCC) is weighing a request to waive spectrum rules for a new ultra-wideband (UWB) device that would operate across a wide swath of frequencies including those used by satellite navigation. The proposal has prompted a call for a wider reconsideration of ultra-wideband limits, a suggestion opposed by the GPS community.

Appropriations Impasse Could Stall U.S. GPS Programs

Appropriations Impasse Could Stall U.S. GPS Programs

The federal government is once again approaching the end of its fiscal year without the appropriations necessary to keep the doors open come October 1 — a reality that could undermine GPS modernization and related programs.

Congress, now in the midst of its August recess, will have just 12 days to sort things out when members return after Labor Day. Under the best of circumstances, lawmakers would almost certainly need to pass a continuing resolution (CR) to extend current spending levels and buy themselves time to hammer out budgetary deals.

Key Lawmakers Move to Make DoD Responsible for eLoran, GPS Backup

A quintet of well-placed lawmakers, tired of federal dawdling, are prepared to make the Pentagon responsible for building and maintaining eLoran as a backup system for GPS. The move could come by the end of the year, possibly through language attached to a must-pass bill.

Leading the bi-partisan charge are Duncan Hunter, R-California, chairman of the House Transportation and Infrastructure Committee, and the subcommittee’s ranking member John Garamendi, D-California.

Officials Delay First GNSS Authorization Request; Light-Squared Tries to Leverage Issue

Officials Delay First GNSS Authorization Request; Light-Squared Tries to Leverage Issue

The U.S. stance on satellite navigation has long supported international cooperation and a degree of interoperability. In 2010 the Obama administration even adopted a space policy that said foreign satnav services could be used “to augment and strengthen the resiliency of GPS.”

That was easier in the abstract, however, when the only fully functional GNSS was GPS. Now, with other GNSS services coming online, American officials want to think things through again.
