RIN INC 2016: Royal Institute of Navigation International Navigation Conference

Main auditorium, Strathclyde Conference Centre

The Royal Institute of Navigation’s International Navigation Conference 2016 will be held at the University of Strathclyde Conference Centre in Glasgow, Scotland from November 8 – 10, 2016.

A number of keynote speakers will discuss topics from Virgin Galactic’s voyage to space to quantum sensors for inertial navigation to autonomous cars, android phones, train control and even "Three dimensional thinking: from rats to humans, via Klingons."

Poster and demonstration abstracts are due by May 30. Full paper submission is due on June 15.

Re-Baseline This!

So, if everything had gone as planned, we would have a new ground control segment (OCX) operating a new generation of satellites (GPS III) as they launch into an expanded constellation in support of modernized military GPS user equipment (MGUE).

But then the best-laid plans. . . .

The “Brussels View” from Prague

Carlo des Dorides, GSA Executive Director

Last October, the European GNSS Agency (GSA) Administrative Board reelected Carlo des Dorides as executive director of the GSA, giving him a second — and final — four-year term in charge of this key agency responsible for supporting the effective operation, maintenance, and security of Europe’s satellite navigation systems. We met with him recently at the GSA office in Prague to learn how he plans to see out his mandate.

Military GPS Receiver Advances Could Help Trim Satellite Costs

Advanced military receivers using the sort of modern multi-channel, multi-constellation capabilities already available commercially, could enable the Air Force to focus its anti-jam efforts on the ground, simplifying future GPS satellites and lowering their cost. Moreover, experts told Inside GNSS, the cutting-edge receivers could be deployed years before the anti-jam capability planned for the new GPS III satellites would be fully available.

Inter-Signal Correction Sensitivity Analysis

Symbols and Acronyms

Modernized GPS satellites give civil users the ability to achieve dual L1/L2 PY accuracy using dual L1CA/L2C ionosphere-free measurements and, with IIF satellites, dual L1/L5 signals. Because broadcast GPS ephemeris data is based on an ionosphere-free pseudorange calculated from dual L1PY/L2PY measurements and the civil signals are not all perfectly aligned to it, new broadcast parameters and a new modernized dual-frequency algorithm are needed in order to align new signals with the dual L1/L2 PY signal.

Listening for RF Noise

GNSS signals are vulnerable to interference due to being extremely weak when received on Earth’s surface. Therefore, even a low-power interference signal can easily disrupt the operation of commercial GNSS receivers within a range of several kilometers.

GNSS Evolutions for Maritime

Trends for marine accidents show rising numbers and costs that are mainly associated with collisions and groundings. Research indicates that about 60 percent of these accidents are caused by human error. The majority of them could have been avoided by providing suitable input to the navigation decision-making process, according to a 2008 report by the International Maritime Organization (IMO) Marine Safety Committee. (See IMO 2008 in Additional Resources section near the end of this article.).

Senate Kills GPS OCX Funding Due to Cost Overruns — Now $5.3 Billion and Rising

The Senate Armed Services Committee zeroed out the Pentagon’s $393 funding request for the new GPS ground control system during its May 11 markup, asserting that the program’s cost overruns — with a total cost that may reach $5.3 billion, up from an original $1.5 billion — had breached the Nunn-McCurdy Act.

Under the act, such a breach could result in termination of the Next Generation Operational Control System or OCX unless the Secretary of Defense goes through an in-depth review of the program and personally certifies its critical importance.
