 APRS logo
Working the ISS using APRS/Packet is different than working through normal APRS/Packet. 
The following will help you get work APRS/Packet using the ISS.  Please read the articles before transmitting.  As I find articles and hints, they will be added to this page. Many thanks to the AMSAT, SAREX and UI-View list users and  maintainers for a lot of this information.

Current ISS callsigns are
BBS - RS0ISS-11
Digi - ARISS
Packet Keyboard - RS0ISS-3 (currently unavailable)

Current info on ISS operations is available at:
http://spaceflight.nasa.gov/station/reference/radio/

Thanks to Kenneth G. Ransom - N5VHO, ISS Ham Radio Project Engineer for the callsign and current info links!
