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

Da Capo: Pardon Me, Boy, Is That the Galileo Choo Choo?

February 1, 2012By

Our Paris correspondent, Ms. Axelle Pomies, writes that “The Galileo Train is about to depart, but European GNSS applications incentives are still at the station.” “Despite a vast potential for industry growth and new jobs in Europe,” she continues, “European government bodies are not taking up the challenge. The budget dedicated to GNSS application research in European Commission FP7 was... read more

Facts, Law, Table, Pound, Hand

January 16, 2012By

So it has come to this. LightSquared officers want the FCC to investigate Brad Parkinson. Senator Joe McCarthy is not a good look for them. A young attorney of my acquaintance, who also happens to be a contributing editor to this magazine, wrote me in this regard: “Lawyers have an old saying — when you don’t have the law on... read more

On-Site Geo-Referencing of 3D Static Terrestrial Laser Scans

June 29, 2011By

By Jens-André Paffenholz This blog presents an efficient procedure for directly geo-referencing static 3D laser scans. This is a worthwhile way to obtain the required transformation parameters from the local sensor-defined coordinate system to a global system. Therefore, a multi-sensor systems (MSS) is designed with a phase-measuring laser scanner and 3D positional sensors (see Figure 1). By means of at least... read more

Where Time and Space Meet

November 1, 2010By
overview

Increasing availability and performance of state-of-the-art navigation sensors motivates the need for a highly accurate reference system commonly referred to as a time-space position information (TSPI) device. The Advanced Navigation Center at the Air Force Institute of Technology is working with the Air Force Flight Test Center to develop a next generation time-space position information (TSPI) system to be used for test and evaluation of modern navigation devices. read more

Kick It in and Push!

July 13, 2010By

By Alan Cameron The Elephant Charge (“Dust, Sweat, and Gears”), an annual off-road motorsport charity event, brings together competitors, their families, and supporters for a wilderness weekend of GPS-driven fun and frenzy in the Zambian bush. I’m for fun, but I always wince when I see folks tearing up habitat in the name of saving it. Elephant Charge 2010 seeks... read more

World Domination: The Sequel

April 19, 2010By

Perhaps we should call this The Interquel rather than The Sequel, as the latter will take place September 23 in Portland, Oregon, during the ION GNSS 2010 Conference. In January, 12 brave individuals joined me in San Diego to see if this thing would work at all.  It did!  The exercise revealed many adjustments needed to the game, but overall,... read more
