Going to the Adriatic in May? Submit Your Abstracts for the GNSS Vulnerabilities and Solutions Conference

Baska, Krk Island beach

This annual seminar on the Croatian Adriatic aims at GNSS experts and
covers the risks and vulnerabilities of the global navigation satellite
systems and efforts to improve accuracy and reliability.

The sixth GNSS Vulnerabilities and Solutions Conference  will take place at Baska on the resort island of Krk in Croatia from May 21 to May 24, 2012.

The Year’s Top Stories from Inside GNSS

If the readership of insidegnss.com news is any indication, 2011 was the year of LightSquared.

Articles about the would-be wireless broadband company that wants FCC approval to set up a terrestrial network transmitting on frequencies next door to GPS and other GNSS L1 signals garnered the most page views on our website for 6 out of 12 months.

Conference Survey Reflects North American Leadership in GNSS Innovation, Delays in Galileo Program

A survey of 140 attendees at last week’s European Navigation Conference (ENC 2011) in London, England, produced a fascinating assessment of GNSS expectations in the coming years — and how that assessment has changed since 2007.

Sponsored by Helios, a UK business and technology consultancy working in the transportation and technology domains, the survey asked delegates eight questions with multiple choice answers, and recorded their responses using handheld keypads and live electronic voting.

LightSquared Postpones International Expansion Effort

A GPS app on a Japanese smartphone. The GPS Council there told the FCC that any signal degradation could jeopardize the Global Positioning System’s standing as a global standard.

LightSquared has dropped, for now, efforts to expand its wireless broadband plans to markets in other countries, Inside GNSS has learned.

The Virginia firm was working this summer on proposals to the International Telecommunication Union, including one aimed at addressing compatibility issues between ground stations or “complementary ground components” of mobile satellite services and other frequency-using services.

Return to main article: "True3D HUD Wins Global SatNav Competition"

Many technologies are created before their best applications are even thought about. This leads to a business phenomenon known as “technology push” in contrast to “consumer pull.” The True3D Volumetric HUD technology did not share this path.

Network RTK and Reference Station Configuration

Q: What effect does network size have on NRTK positioning?

A: Network real-time kinematic (NRTK) positioning is nowadays a very common practice, not only in academia but also in the professional world. In the last 10 years, several networks of continuous operating reference stations (CORSs) were created to support users. These networks offer real-time services for NRTK positioning, providing centimeter-level positioning accuracy with an average distance of 25–35 kilometers between the reference stations.

Staying In Lane

Staying In Lane

Next-generation car navigation may well require the ability to identify the lane in which a vehicle is operating on a motorway. This could support advanced driver assistance in general as well as the observation and study of driver behavior and traffic flow. Such road vehicle applications call for sub-meter positioning accuracy, often in real-time — all this preferably at low-cost.

A San Francisco Bay Area company — Making Virtual Solid–California (MVSC), which snared a trio of awards in a global GNSS competition for its novel approach to driver assistance, is still in early phases of development.

The origins of the company, however, go back more than 40 years to the Cold War era when its principals, Chris Grabowski and Tom Zamojdo, were studying physics and theoretical mathematics at the University of Warsaw, Poland.

But more about that later — first, the news.
