[time-nuts] GPS interference and history...

I would expect Lightsquared would attempt to acquire space on existing towers
rather than build their own but I have no insight into what Lightsquared is
planning to do. The US has a relatively mature tower industry that caters to
cellular type providers. .

So back to my original question (I didn't mean to spark such a debate)...
These 40,000 transmitter towers... Are they merely talking about attaching their
antennas on existing cell towers or totally new
FWIW, perhaps there wouldn't be as much of a fiasco if every other navigation
and timing technology didn't get phased out in favor
of GPS... There literally is no backup sans a fold-out map or sun-dial... To say
it is 'key' or 'critical' is an understatement.
Likewise, I don't like the idea of existing L1 devices becoming scrap to merely
support someone's cell phone / broadband addiction.
There's too much hardware out there to make replacement impractical short of a
decade long transition period. Even then during that
transition period lord only knows how many millions (billions?) of dollars it
will cost to replace / retrofit existing hardware.
Who's going to pay for all that?
If I can put a $5 filter on my incoming antenna line to make it reduce most
interference from L^2 and I loose maybe one satellite
out of eight visible, I'll be content with that... If I have to put a $100
filter to pray I can get signal for an hour a day...
Well... L^2 is going to have mysterious constant hardware failures in this area.
