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!
