Here's a story about "LocataLites" or GPS units that are accurate to a few centimeters even in places where satellite signals are blocked. This could be the next generation of GPS.
Many applications
Very interesting. That opens a large field of possible applications then where such precision positioning is necessary. Agriculture is one, but also many kind of surveying and explorations, alignment of large scientific equipment, etc.

Plus you can really find out where your kids are!

Interesting concept but never really going to >>>

replace satellites; too accessible to mischief makers, etc.

Very cool
Very cool to think that this might bring high accuracy gps down to consumer level cost.
Isn't this basically what surveying accuracy gps equipment does now but with expensive, limited availability equipment?
It's about the Line- If a line can be drawn between the powers granted and the rights retained, it would seem to be the same thing, whether the latter be secured by declaring that they shall not be abridged, or that the former shall not be extended.
I'll bet
I'll bet we'll never see them here as they operate in LightSquared's frequencies.

Interesting!
Interesting technology, but doubt if it would be generally available across the US. The general public probably doesn't need that kind of accuracy and wouldn't pay the expense of implementing it nation wide. And as TMK said, they'd be a great temptation for troublemakers.

I don’t know what they are using now but in the mid 90’s I set up a Trimble base station at the BLM District Office in Butte, Montana.
A computer at the office recorded satellite readings 24/7. BLM and Forest Service surveyors would mark locations in the field with their “roamer” units and come to the office to network to the Base Station computer and use very expensive Trimble software to join both sets of data to get more accurate locations than could be had using only the roamer units.
I also set up a telephone modem and software at the Base Station Computer that enabled BLM and Forest Service surveyors at other offices to download the base station data to their local computer.
They could choose periods of time for which they wanted data so that they would not have to download the full data set.
Thanks for the very
Thanks for the very interesting article.

gps
Thanks Brentrn verry interesting
I may have my user name and password confused or switched! Can I get confimation of my user name????
not a replacement
from the article, a device can cover several kilometers. This may have some limited application, but to have that many devices to cover the entire US seems very impractical. And, with that many devices, maintenance and outages could be problematic.

Can't wait for this to hit
Can't wait for this to hit the retail space!
How can you say that?

I'm sorry, but I beg to differ. It would greatly aid me in my nighttime crop circle escapades after harvest season.

Déjà vu
Sounds like WAAS that has been used for a long time, plus the A-GPS that has been used by the cell phones.
It all come back to, there is nothing new under the sun, just different packaging.
I could mow grass at night.

It reminded me of D-GPS first (http://en.wikipedia.org/wiki/Differential_GPS), but it's like WAAS too. Did these guys re-invent the wheel, or create a knockoff of it without telling anyone?
