LightSquared sessions at Survey Summit: A possible solution?
American Surveyor    Share    Share on FacebookTwitterShare on LinkedinE-mail article
During the plenary session at the Survey Summit, Jeff Carlisle (a LightSquared VP) and Peter Large (representing the Save our GPS Coalition) each presented their case. Carlisle stated repeatedly that LS started the process 10 years ago, and that all interested parties — including the GPS manufacturers — were well aware and signed off. More

NTIA highlights just how bad LightSquared interference is

Late last month, LightSquared finally filed its revised testing report with the FCC, which unsurprisingly confirmed that its planned LTE network would significantly interfere with GPS signals. LightSquared recently proposed an alternate solution that would utilize a 10 MHz swath of L-band spectrum in the lower portion of the company's spectrum assets, instead of the chunk of 10 MHz spectrum they had planned to use — but showed significant GPS issues.

Final report of FCC working group: Lose LightSquared from L-band
GPS World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The final report to the Federal Communications Commission on three months of research by the technical working group tasked to investigate and analyze effects of powerful terrestrial L-band transmitters on the GPS signal and services finally appeared on June 30, nearly two weeks after its assigned date. The facts are clear: the LightSquared signal would devastate services for users of all GPS receivers tested. More

LightSquared hires former lawmakers to get satellite plan off ground
The Washington Post    Share    Share on FacebookTwitterShare on LinkedinE-mail article
LightSquared said it has brought on two former federal lawmakers as advisers as the satellite broadband start-up tries to overcome obstacles to its network plans. The firm, created by hedge fund investor Philip Falcone, said former senator Byron Dorgan of North Dakota and former representatives George Nethercutt of Washington and Charlie Stenholm of Texas have agreed to lead a program to find ways to bring its satellite-based LTE service to rural areas.

Teachers teaching teachers GIS
GIS User    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Many of us in the field of GIS believe that spatial analysis needs to be spread throughout a wide variety of disciplines. In other words, our philosophy is that the geographic way of viewing the world and geospatial tools are too valuable and useful to be confined to one discipline, whether it is geography or computer science or another single discipline.

Tech talk: State plane coordinates
Point of Beginning    Share    Share on FacebookTwitterShare on LinkedinE-mail article
There was a time (in the 1980s and prior) when "everyone" knew about State Plane Coordinates, including how those systems were set up and how to use them effectively. Or so we thought. The reality is that although most surveyors knew State Plane Coordinate Systems existed, that's where it stopped for the vast majority. Those who knew the operational details of proper application were pretty much only those who were required to do so. More

Evaluating open source tools for hydrological analysis

Located in a small valley in Southwest Germany, the Linach dam was constructed in the 1920s as a hydro-electric plant for the municipality of Vohrenbach but closed in the 1960s. Now reopened for recreational use, issues such as flood protection as well as landscape preservation had to be considered as the area lies within the Southern Black Forest nature reserve. More

GEOID09 in middle Tennessee
Professional Surveyor    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A weather report calling for weekend rains totaling more than six inches in a 24-hour period was just the start of trouble for those of us living in middle Tennessee at the end of April 2010. All we could do was stare at the TV as authorities warned everyone to stay home. Reservoirs were flooded to capacity, portions of the interstates turned into rivers, and thousands of residents were displaced from their homes. More
