APRS has standardized an ID series for amateur radio OSCAR spacecraft – APOxxx

At the request of Juan Carlos, LU9DO, AMSAT-LU wanted a series of APRS designators for uniquely identifying AMSAT APRS applications.  He suggested those beginning with the letter O for OSCARS.

ALL APRS applications include this identifier in their packets so that the source of APRS data can be known.  See the list at
