APRS via satellite

Is there any activity via satellite of APRS traffic on 145.825MHz? My 2 ground-stations don’t require any monitoring so I have been out of touch with developments.
I live in a NSW regional area with not much amateur radio activity. I built an Igate to get me into the IS network. I persuaded a ham friend and we build an Igate for him so now I’m thinking of converting my Igate to an Sgate.
Will I be wasting my time?
Besides changing frequency and the beacon description, do I need to make any other changes to my direwolf.conf file?
