Hopefully we have dodged the bullet and this post can be marked up as "paranoia"
Potential threat of GPS disablement! I know this has been an ongoing issue for a while. A company called LightSquared has been trying to build a cellular network that interferes with GPS. You don't hear much in the news about it these days, but it seems that maybe the threat has not completely gone away yet.
Although LightSquared was denied the frequencies after building out much of a network and had to file for bankruptcy, they are still petitioning the government to try to get a deal that would allow them to use some of the frequency's that are a little further from the GPS frequency. And apparently some venture capitalists seem the think that somehow the network could be resurrected and salvaged. Still there is a strong resistance from the Airforce, Trimble, and others, but I am worried that the power of big money could prevent this threat to the GPS system from going away.
Does anybody have an updated status on this issue?
When I hear about problems with GPS inaccuracies and runaways, I wonder if testing of the lightsquared network might be going on, or similar cellular interference could be a factor.
Interference on GPS and other links we use in out UAV's bring to mind the concern as it already applies with existing RF sources in our environment. There is a spot I would love to do a fly around getting some nice video, but a cell tower and some other towers sits on the top of the hill that I want to video, along with various other frequencies such as 2 meter, 70cm, GPRS an cellular services from Sprint, AT&T and maybe others. Probably not a good place to fly!
Anyway, the LightSquared technology is referred to in some articles as LTE, I know that LTE is been deployed around the country, so it doesn't seem to be the same LTE that light squared plans to deploy is it? as far as I can tell, so far they have been blocked from deploying the GPS blocking technology and lets hope they continue to be blocked!
Here is the latest thing I can find on it right now on the position of the FCC:
Anyway, hopefully, like I said: we have dodged the bullet..
