The Kinematic GPS Challenge: First Gravity Comparison Results

March 14, 2012By

By Theresa Diehl The National Geodetic Survey (NGS) has issued a “Kinematic GPS Challenge” to the community in support of NGS’ airborne gravity data collection program, called Gravity for the Redefinition of the American Vertical Datum (GRAV-D). The “Challenge” is meant to provide a unique benchmarking opportunity for the kinematic GPS community by making available two flights of data from... read more

Brave New World of Data via the Cloud

February 29, 2012By

The frightening thing about the Mobile World Congress in Barcelona, the bloody awful frightening thing is the sheer amount of data talked about, enthusiastically envisioned, planned for. Planned for in the sense of throwing up business cases and wheeling and dealing new products and services for millions and billions of users that will pump vast amounts of data, countless numbers... read more

February 28, 2012By

Smartphones are taking over the world, and not just modern industrialized societies. A Broadcom executive predicted today at the Mobile World Congress in Barcelona that, with costs going down for less expensive models, smartphones will not only be the first phone of any kind for many people in India and other developing nations, it will constitute their first Internet experience.... 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

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
