APRS/MIR test Quick Look



Hopefully this quick summary might minimize the number of other stations
that will feel the need to post duplicative results.  A full analysis will
be published in the AMSAT Journal..  

Since R0MIR was QRT during the two designated APRS/MIR test orbits, the
MIREX team authorized an extended test during the next orbits over the
USA.  All of these passes occured between about 0230 to 0730 local times
meaning lots of sleepy operators...  This is only a QUICK summary,
representing only what was observed on the East Coast.  Full logs are
published on the aprssig only.

During the day of the APRS/MIR test, the live APRServe web page which
shows all APRS packets heard nationwide via all of the remote tracking
stations, www.aprs.net, scored a maximum over 11,000 hits and the peak
load was 155 simultaneous users.  When the APRS packets finally began
being digipeated via MIR, the special APRS/MIR page began plotting
stations instantly (www.aprs.net/mirex.html).  Being able to see a MIR
packet event live worldwide via the WWW without a radio is one of the main
attractions of the APRS/MIR experiment for schools.

OOOPS, just checked page again at 1330z and it seems to have crashed.  But
will be reloaded with resuults...

Most of the APRS stations were home stations (due to the sleep time of the
actual tests) but 5 mobiles and 1 Naval Academy boat were seen.
