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 Lights...

what about the rest of us GPS users?
It's not clear to me in this story, what this means to ME...
What about my GPS? Is this technology going to be applied to LightSquared's equipment so that it will not interfere with ANY other GPS equipment, or is it going to be provided or installed on major GPS equipment/groups/entities in order to overcome the interference from LightSquared?
Anyone have any clarification?
