Amateur Radio Stations heard via ISS
This page documents Amateur Radio data digipeated by the International
Space Station. In order to appear on this page, a position report in a valid
APRS format must be digipeated through ISS, then be heard by an internet gateway
station, which then forwards it on to the APRS Internet System. All APRSIS data is
archived on this machine. Packets that came through the ISS are recalled for this
display. For more info on the technology involved, see the links at the bottom
of the page.
The system will also show those stations that have been heard via ISS but have
not sent a position report in the table at the end of the page.
If you are able to transmit through the ISS digi and wish to send a packet that will make
your position appear on these maps and those of APRS users of ARISS, see:
http://www.aprs.org/iss-faq.html
The biggest weakness in the system right now is the lack of Internet Gateways, or IGates.
Almost all APRS programs have the ability to function as IGates, consult the documentation
of your program of choice for details...the more the better!
The current position of ISS, as well as the 5 and 10 minute future positions are also
shown on the map.
Regrettabbly, because of the huge cost increase recently implemented by Google for its mapping service, google maps are no longer available.
