LightSquared Says It Has Cheap and Easy GPS Fix
I found a picture for the non-techy out there
This illustrates the GPS industry's failure as well as anything I've ever seen:

Look at the graphic halfway down the page. The orange 'McDonald's" symbol on the left is where LightSquared wants to broadcast. They have compromised to only using the left lobe labelled "10L" for now.
The Yellow is a higher-grade GPS reciever, and the Blue is a modern-day consumer GPS reciever (Cell phone, Garmin, TomTom, etc.)
The Black is the new (not-stupid) JAVAD GPS filter design.
The Yellow and the Blue are only "supposed" to work between 1559 and 1591 MHz (labeled at the top of the graphic) but they built such crappy hardware that they're failing to stop accepting input from the "10...

Pretty picture.
But I noticed its from Lightsquared (hardly a reliable source in this issue)!!
The facts are that GPS exists and is in use TODAY. Bandwidth overlap and leakage are KNOWN variables and should not have come as a surprise to Lightsquared.
Existing GPS units and users should not be negatively impacted because of Lightsquared lack of research.

Nor should LightSquared's vision (and LEGAL spectrum rights) be trampled underfoot by the faulty, sloppy business practices of the spectrum thieves known as the GPS industry, right?
And- it's not a LightSquared document, it's a JAVAD Incorporated document. Their last press release (right before the current one) is probably one of the most scathing criticisms of LightSquared I've seen a CEO put his signature on!

JAVAD is no long time bedfellow of LightSquared- they're just the first GPS maker to be reasonable about ...
