SPOT - personal locator service

anyone know more about how these things work
with no external antenna...
Also - looking at the global coverage map - it's interesting,
in that it is mostly the northern hemi - but not over the complete oceans ??

FYI - had read about this new device in a Backpacker magazine.
Here it is live -

ahhhhhh - should have read the "about us" first :)
http://www.findmespot.com/AboutUs.aspx

SPOT Inc., a subsidiary of Globalstar, Inc., (NASDAQ:GSAT)
provides lifesaving communications technology
that allows users to communicate from remote locations around the globe.

They are GPS receivers which can transmit (only) location fixes to the
GlobalStar network of low earth orbit satellites, in tracking mode a new
fix is transmitted every 10 minutes. The orbits have been arranged to
provide continuous coverage for satellite telephone in specific areas,
hence the gaps.

A number of glider pilots I know use them so others can keep track of
their flights. Tracking fixes from a glider over the U.S. appear on
their web site every 10 to 30 minutes, at times (for unknown reasons)
there are gaps of an hour or more. Overall, glider pilots are happy
with them, hikers, boaters, etc., will probably have differing
experiences...

I was just amazed that it could transmit any kind of token signal to a
satellite,
even a LEO type -

I think I saw it on TV,

along with reading about it in Backpacker.
