Global Navigation Satellite Systems Engineering, Policy, and Design
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).

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.

U.S. Representative John Garamendi. U.S. Publishing Office photoA 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.

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).

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.

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.

But the issue reared its head again in Brussels recently, in a highly charged discussion hosted by the European Economic and Social Committee (EESC).

The U.S. Air Force and its mission partners successfully launched the 10th Boeing-built GPS IIF satellite aboard a United Launch Alliance Atlas V from Cape Canaveral Air Force Stations today (July 15, 2015).
The spacecraft is destined for plane C/slot 3 of the GPS constellation
The launch almost coincided with Friday’s 20th anniversary of the declaration of full operational capability (FOC) for the GPS constellation, which occurred on July 17, 1995.
Just two GPS IIF satellites remain to be launched — Atlas V rockets will be used to launch both.

New QinetiQ PRS-capable receiverBritish manufacturer QinetiQ has today (July 14, 2015) announced its progress in developing a GNSS navigation receiver that can process encrypted Galileo Public Regulated Service (PRS) signals.
The multi‑constellation, multi‑frequency receiver is a significant step in the company’s GNSS technology development, says QinetiQ, which expects to bring to market by 2020 end-user products for navigation, tracking, and timing based on the new receiver design. That timeline parallel’s the Galileo program’s current schedule for completing its satellite constellation.
