PTTI 2016: Precise Time and Time Interval Meeting

The Precise Time and Time Interval Systems and Applications meeting is technical conference held each year for PTTI managers, system engineers and program planners. It will be held at the Hyatt Regency in Monterey, California on January 25 through 28. It is sponsored by the Institute of Navigation (ION).

In 2016, for the first time, PTTI will be co-located with the ION International Technical Meeting. Registration for one event entitles attendees to attend all sessions of both events.

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

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.

Most Railroads Will Miss Deadline for Implementing GPS-Aided Positive Train Control

Only a small percentage of railroads are expected to obtain system certification and complete implementation of GPS-aided positive train control (PTC) systems by the current deadline at the end of this year, according to a recent report to Congress by the Federal Railroad Administration (FRA).

Experts: Exclusion Zones Around GPS-Interference Problematic; LightSquared/GPS Lawsuit Settlement Talks a No-Go

In the same week conflicting court filings underscored the intractability of the fight between LightSquared and GPS receiver manufacturers.

Meanwhile, a key technical group found that aviation likely would be hampered — yet not fully protected — by exclusion zones around wireless broadband transmission towers using, as LightSquared has proposed, frequencies adjacent to GPS bands.

LightSquared Submits GPS Market Study to FCC

A “GPS market review” submitted to the Federal Communications Commission (FCC) this week diverges in methodology and results from a preliminary study of U.S. benefits of the Global Positioning System provided earlier this year to the National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board.

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.

Federal Cuts Expected in Civil GPS-Related Programs

In sharp contrast to the strong support given to the military’s satellite navigation programs in the next fiscal year, Congress is considering cutting every GPS-related programs supported by the Department of Transportation (DoT).

GPS Military Programs Well Supported, But FY16 Defense Bills Face Veto

With just weeks to go before Congress disperses for a month-long break lawmakers have yet to finalize either a defense funding bill or legislation authorizing military spending for fiscal year 2016. The way forward looks particularly rocky as enacting both bills will require resolving a yearslong fight over spending caps.
