Re: Truth or FUD? Yes it's true. They've long sold receivers for years that were susceptable to signals outside the GPS band, even though they were told by the FCC years ago that those bands wouldn't stay vacant for long, and they better prepare for the day when those bands get allocated.
What did the GPS do? Nothing. They stuck their heads in the sand. They continued to sell cheap, poorly designed receivers into the marketplace, even though the FCC told them that in a few years they would be experiencing interference. Unfortunately, receivers don't emit signals, and the regulatory ability to do something about them is limited; e.g., if you want to sell crap receivers, you can. The GPS industry decided they could instead wage a PR war, as that would be the less expensive way to deal with it, and most people don't understand the issue. From the sympathetic reception they've gotten from most places, including this website, it appears to be working.
FCC Class B Notice: "must accept any interference received& Wait, what do you mean that FCC couldn't do anything about crappy receivers? Lemme quote something that most people should be very familiar with reading:
FCC Class B Notice
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause undesired operation.
Does the second part not actually mean anything?

Re: Truth or FUD? Sorry but the bands we are talking about were use by other satellites and even satellite phones.
Other sateillite use will not jam GPS so no buffer was needed.
GPS signals red shift 25 mhz into the specturm lightquared wants to use. That is the laws of physics and nothing can change that. Lightsquared was well aware of this limitation before they leased it.
Lightsquared leased the satellite only spectrum to offer sateillte broadband, they are changing their plan after the fact to try and use ground transmitters as they will make them much more money than satellite broadband.
They took a gamble and lost.
There is nothing the GPS industry can do.
Also all US taxpayers OWN GPS not the GPS industry.
We have been paying for GPS since the 70s. Lightsquare is trying to screw the US out of our investment.
