A real-time ish as in non actionable but rather a past tense indicator the usage of LEO satellites is pass audio/waterfall data available through the satnogs network (
network.satnogs.org). If you wanted satellite transponder awareness in realtime, I'd recommend an omnidirecditonal antenna and brewing your own software suite for it, though that's probably a bit ambitious. QO-100, which is a GEO transponder much like the OSCAR-0 (the moon) has a web SDR in Europe that gives real-time actionable information about the usage of the narrowband transponder for SSTV, SSB, CW, Data, and the like. They even have a PSK net. Unfortunately, I see you're in FM03 and the USA gets basically no use of QO-100 whose footprint barely covers some of Brazil. Skeds tend to be orchestrated via this listserv or oftentimes discord (Amsat or r/amateurradio or even HRCC's Flying Space Radio Channel), but I'm unaware of an integrated chat/sked coordination service for amateur satcom.
