Not really. A lot of navigation is done in coastal waterways and
inland rivers, some of it at night or in reduced visibility.

It turns out that one of the best connected opponents to the proposed
Lightspeed service is tractor manufacturer, John Deere. Apparently a
lot of new farm tractors are equipped with precision GPS units for the
purpose of accurate seed planting and other hi tech applications.

Farmers have been using GPS guidance devices for years on their planting
and harvesting rigs. I see no reason to allow Lightspeed or anyone like
it to disrupt a service needed by many sectors of the economy.

Been going on for a long time. GPS grids are running tractors, plowing,
planting, and working millions of acres with no drivers...

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.

The report can be found at: http://preview.tinyurl.com/7jyaazf

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

Car satnavs may be affected, but that's off topic.

Have you ever tried to drive your care in pea soup fog with a GPS?

Boaters try and do it all the time.


I've always found that a smile drives my cares away.

Is that what your psychiatrist taught you? Are you working on your

Holy cannoli ! Robotic tractors? Hope none of them have been

Well, I think they must use something to aid the GPS because iirc the
tolerance of GPS is +/- 30 feet or something like that...

The increased yield from using GPS in farming is amazing.

One can get accuracy to 3 ft, and even to 6 inches. Just have to throw
money at it.

Years ago, before GPS, my company did a custom radio control for a
local cane farmer's tractor, with all the necessary failsafes. He
would drive the harvester and the R/C tractor with a fifth wheel
trailer alongside. When the trailer was full, he'd drive the tractor
to the pickup site, disconnect and hook on an empty and continue.

He was able to stack 'um up for the trucks to pick up all by himself.

Just with GPS? I was told the closest they could "tune" the atomic
clocks in the sattelites created a sloppy area. "That's why they can't
land a jet on an Aircraft Carrier with GPS alone, it can't account for
the pitch of the deck"...

Was this GPS alone, something else, or a combination??
