APRS already has 3 LEO's in orbit and three more that are manifest. These
extend the APRS uplink capability to everywhere on Earth and the LIVE feed
from the satellites is available on http://ariss.net and
http://pcsat.findu.com and the live feed everywhere else is on
http://aprs.fi . So, in addition to all the HF IGates, and the VHF Igates
and the Satellite Igates, there is worldwide uplink potential (that is
"uplink" into the APRS network where then it gets parsed into the OUTERNET
I am only talking about amateur radio content, nothing else meets our rules,
but as a 2-way emergency communications capability with more than 2 million
licensed amateur radio operators worldwide, it does have potential within
our rules. And it lets OUTERENET support a low cost 2-way global
communications at virtually no cost to them either.

And we don't have to stream the entire APRS global feed! Only packets with
the PATH of "OUTNET" in them. So any ham, anywhere on earth, can route his
packet via the APRS satellite, or HF, or VHF terrestrial network and then
have it routed into the OUTERNET uplink by including "OUTNET" in his path,
and it will get sent on the OUTERNET uplink stream and hence to the OUTERNET
GEO downlink. Thus, a 2-way system for Amateur Radio and their Emergency
The current APRS Satellite traffic is about 1000 packets per day and all are
visibile on the above TWO satellite feeds. That works out to about one
packet per minute or about 1 byte per second. 1 Baud would not be too much
to ask of OUTERNET. Of course, if they turn it on for us, then the rate
might increase TEN fold or in a few years, ONE HUDRED FOLD... To 100 baud.
Or even one THOUSAND fold and the bit rate would be up to only 1 kbps or
less than 1% of their traffic! Oh, and that is supporting thousands of
two-way amateur and emergtency communicators globally anywhere on earth!
