IFEN GmbH and WORK Microwave have announced a new round of enhancements to the NavX-NCS line of GNSS multi-frequency simulators.
Increased usability and control is achieved through the new NCS Control Center software release V1.7, according to the Germany-based companies. The GNSS simulators now feature motion models that simulate the physical behavior of various types of vehicles or vessels, including airplanes, trains, cars, trucks, and ships.

[Updated March 26, 2012] Six experts debatd the exciting – and controversial – claims of faster-than-light neutrinos from physicists who used the Large Hadron Collider (LHC), the world’s largest particle accelerator, in a European experiment that called into question the basics of modern physics.

The 2012 European Satellite Navigation Competition will accept your idea, innovative service or business plan for GNSS applications beginning April 1. Submit your idea online at www.galileo-masters.eu through June 30.
This year, the competition is working with 20 partner regions in Europe, Brazil, the Middle East and North Africa. You do not have to be a resident of the partner regions in order to enter, however you must anticipate basing your business in one of them.

Whenever the annual Munich Satellite Navigation Summit came around, some GNSS program was usually in the ascendant, while others had reversed direction or found themselves treading water. This year, perhaps for the first time, all four major providers had reason to celebrate as the event’s organizers cut the cake at their 10th birthday party.

The British Royal Institute of Navigation has given prospective authors a May 4 deadline for abstracts for its annual conference, NAV12. The theme this year is "GNSS and Beyond."
Authors have a broad choice of navigation and technology topics from GNSS, eLoran and integrated systems technology to satellite navigation vulnerabilities to jamming and space weather to low-cost consumer apps design.

Q: What is Coarse Time Positioning and how does it work?
A: Coarse time positioning is used to provide a position fix using inaccurate time information when tracking sufficiently weak GNSS signals such that the navigation message cannot be extracted reliably. This article presents the key aspects of coarse positioning, including some of its challenges. To start, however, we begin by looking at the role of time within a GNSS receiver.

Over the last few years, several of us in the GNSS community have done our best to convince our colleagues, policymakers, and the general public that unsavory characters with GNSS jammers or spoofers are a genuine threat to GNSS and an orderly society.
"But who would want to use a jammer or spoofer?” people ask.
My response? Hackers, because they can. Thieves planning to snatch expensive cargo. A moonlighting employee in the company car. Worse yet, state actors or terrorists targeting our national infrastructure.

LightSquared announced today (February 28, 2012) that Sanjiv Ahuja has resigned his position as chief executive officer of LightSquared, Inc. He will continue to serve as chairman of the board.
Ahuja’s resignation is the latest development in the company’s attempt to establish a nationwide terrestrial wireless broadband network in spectrum adjacent to that used by GPS and other GNSS L1 services. No explanation was given for his departure.

On any given day — especially cloudy winter days — most people may not give a lot of thought to the Sun.
More than 150 million kilometers (93.2 million miles) away, its remoteness belies the enormous forces at work in this yellow dwarf star with a mass 330,000 times that of Earth. If someone asked us to name its harmful effects, we might come up with sunburn, heat stroke, skin cancer.
But many in the GNSS community know better.

Charging the Federal Communications Commission (FCC) with a “rush to judgment,” LightSquared Inc. is seeking an extension of more than a month to comment on the FCC’s intention to prohibit the company from building a high-powered wireless broadband network in RF spectrum next to GPS and other GNSS services.
