Lawrence,

I would try to see if a 1.8m dish would be enough to receive MSG-1 in C-band from Atlantic Bird, if I were you. Just pure curiosity, as I think that the data is an exact bit dump of the HotBird data.

Actually, I am quite convinced that the Fucino uplink station in Italy receives HotBird, dissects the DVB data and then feeds it up to Atlantic Bird, as simple as that. No need to get into the weeds of the DVB payload, just copy bits!

Bye, Luca

Lawrence,

My history with MSG-1 doesn't go back far enough! At the time when
MSG-1 was being planned, were there even any satellites providing
any digital transmissions for domestic users? It was all analog
until quite recently wasn't it? So no cheap Technisat cards! We
should all thank that power amplifier that failed!

Cheers,

Essentially, the NOAA polar orbiters provide digital (h.r.p.t.)
telemetry even if (as must be the case) the original optical image is
sampled digitally for coding and transmission. I would think of PDUS as
being all but digital - I think that it is a matter of different
definitions. MSG-1 is simply an 'all-digital' satellite as compared to
Meteosat-7 and earlier sats being a mixture.

I set up a PDUS system and operated it until we moved to Southampton. I
am only now beginning to dismantle the 1.8m dish because I cannot now
see it being used.

Lawrence
