If you go to http://aprs.fi/?call=ISS* you'll see that there are any
number of ISS* objects, none of which are actually mine because mine
travels too fast and get's knocked out by Hessu's speed filter.
Your 1303 is actually
http://aprs.fi/?call=a%2FISS_%201303&mt=roadmap&z=11&timerange=3600&_s=ss_call
or an object being injected by EI3RCW-3
(http://aprs.fi/?c=raw&call=EI3RCW-3) who is apparently running Digi-NED
(APND13) which IIRC has some features of tracking satellites and locally
transmitting AOS information for the surrounding area.
It sure would be nice if all of these folks transmitted such local-only
objects with NOGATE or RFONLY in their paths!
