NTIA Thumbs Down LightSquared; FCC Concurs

February 15, 2012By

“We conclude that LightSquared’s proposed mobile broadband network will impact GPS services and that there is no practical way to mitigate the potential interference at this time.” These words from Lawrence Strickling (right), U.S. assistant secretary for communications and information and head of the National Telecommunications and Information Administration (NTIA), appear to signal the end of LightSquared’s run. Strickling’s letter... read more

Inside the Head of the Body Politic

February 7, 2012By

In the exciting run-up to Election ’12, we conducted a straw poll of selected voters, giving everyone a chance to see what the electorate thinks about the state of things, and its outlook on the future. This is y’all talking, now: a barely scientific subset of the GPS/GNSS community, the audience at last week’s webinar, “The Challenges of Global Navigation.”... read more

A Comparison of Lidar and Camera-Based Lane Detection Systems

February 3, 2012By

By Jordan Britt, David Bevly, and Christopher Rose Nearly half of all highway fatalities occur from unintended lane departures, which comprise approximately 20,000 deaths annually in the United States.  Studies have shown great promise in reducing unintended lane departures by alerting the driver when they are drifting out of the lane. At the core of these systems is a lane... read more

Innovation: GNSS Antennas and Humans

February 1, 2012By
FIGURE 6. Gain pattern of the patch antenna as measured by the measured C/N0 at all elevation angles as a function of antenna distance from body. Elevation angles [0º, 90º] have azimuths [180º, 360º], while elevation angles [90º, 180º] have azimuths [0º, 180º].

A Study of Their Interactions
A team of researchers from The University of Calgary report on tests conducted on two different types of GPS antennas operated in the vicinity of a human phantom — an artificial body with similar electromagnetic properties as that of a real human. read more
