Iss as a station ? 

I was worried about that 

Iss is not a station 

Iss is an object 

Illegal ?

> Ok, before I change the ISS from an object to a station, and possibly start beaconing live positions for any queried satellites, I'd like to get a consensus from the aprssig.  I made the ISS satellite an object sourced by KJ4ERJ-15 to provide for trackability and to adhere to the established norms (as I saw them, at least) that stations were "real" and objects were "manufactured".  Yes, they may be designed to be displayed the same, but there was some resistance to making RFID-implied locations "stations" rather than "objects" as it was somehow deemed "spoofing" something that wasn't really APRS.

> So, Satellite Objects?  Or Source-Calls / Stations?  Weigh in with your opinion on the list or off and I'll see where the consensus lies in a few days' time.

> Oh, but the posits will have a MultiLine encoding (http://www.aprs-is.net/WX/MultilineProtocol.aspx) of their approximate coverage area so that clients that support such displays will be able to see it.  This will appear as random characters on non-supporting clients, unfortunately.
