Boat Forum / Cruising / November 2004

The real limitation is that APRS runs over 2m Radio, which is in the
same frequency band as your VHF Radio, with the same distance
limitations.  Thus, in order for this to work, you need to be within
range of a shore station, or have a working internet connection.

There is one exception to this, that I am aware of.  The International
Space Station has Amateur Radio gear onboard, and as part of this they
are running an APRS station. (see http://www.ariss.net ).  If you are
running an APRS station, the ISS is overhead, and the ISS is also
within sight of a shore station, then your position will be reported to
the internet.  You will also receive position reports of everyone else
who is digipeating by way of the ISS.

The other side benifit on fbeing in this situation is that you might
get the chance of talking to one of the Astronauts as they go by, as
all the astronauts who fly on the ISS are licensed amateur radio
operators.  Though, this will only be possible if they are on break,
and are using the radio.  But your chances are pretty good in the south
pacific, as ther earen't many other people for them to talk to. <G>
