BusinessWeek is carrying an article today that says that government
tests showed that the proposed LightSquared mobile service caused
interference to 75% of all GPS receivers tested.

There is big money behind this. I'd recommend writing your elected
representatives and voicing your concerns.




It seems to me real sailors needn't be concerned about this at all.
Who
needs GPS inland or very near coastal anyway where landmarks and
navigation marks are eyeball visible? Those who proceed down the
Intracoastal Waterway with eyes glued to their GPS readout are putzes
to
be sure.

It's obvious you haven't sailed at night.



Nighttime is for anchoring or docking when one is recreational sailing
inland waterways. And, even if one likes to take unnecessary chances
recreational sailing or even if one sails for a living commercially,
since the interference is only within 100 meters of a transmission
station, it will result in a GPS not being accurate for all of about
five seconds (your sample rate is probably not much greater this this)
when you're underway should you happen across such a station right in
the middle of the channel.

The concern about vessel navigation being compromised by this is a
laughable one.
