It will remain at 0� until at least the end of 2005. MSG-1 will be moved to approx 3-4�W, subject to final Eumetsat Council approval. This is possible because there will be no direct dissemination from MSG-1. and hence no co-interference. At that new position images corrected to 0� (as they are now) will show less interpolation than at present. Seems a good compromise. Regards Douglas.

MSG-1 and MET7 thoughts
Luca Bertagnolio <lucaberta@...>
Hi,
I was just wondering, since the direct downlink of the data from MSG- 1 will not be possible, what would prevent Eumetsat from positioning MSG-1 close by 0 degrees, let's say 0.5E, and run the operational service from that position? Doing that would enable a longer transition from the analog MET7 broadcasts, which are received by a very large number of stations, keeping MET7 at 0 degrees, while MET8 would already be operational with almost the same coverage. Of course I am only talking about technical matters, not taking into consideration agreements for orbital slots and things like this. Does anyone know how the transition from analog WEFAX to the new format is handled? I would not be surprised to see quite a few protests when MET7 will start to drift towards 10W... Bye, Luca

There is nothing specific in any of the technical documents (Particularly 07 and 08). MSG's power demand (600W) is 3 times that of its predecessors but still has an increased life span of 7 years. There is a reference to on-board batteries for eclipse purposes but I would think that it is to ensure power for its own housekeeping etc. Having said that there is no input/output dissemination now so the power requirements must be less. Will be interesting to see what happens. Douglas.

Eclipse periods
Will MSG-1 have eclipse periods like other geostationary satellites,
when there is not enough power to keep the electronics fully running? I am presuming so, but have seen no announcement as yet. I also asusme that at some point there will be periods where the imager will be switched off to avoid looking at the sun. I see this will start soon on GOES and Meteosat 7. Cheers, David

Low sun (early and late) is excellent for cloud topography etc. so a 6 hour bit in the middle of the day really is not good enough. One difficulty is the judgement of how the northern hemisphere will look (in visible) during the winter months although the appearance of the southern hemisphere over our summer has given some clues. Permanent Europe with the lower segment following the sun ? That would ensure visible images for tropical cyclones in the Madagascar area and of course the formation of tropical depressions/storms/hurricanes in the Atlantic. Douglas.

Re: New group - and some questions

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,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. regards Lawrence

true enough, for us lucky ones that live in the footprint of Hotbird. I have good result with a 40cm dish (when it's not windy or rainy!) The C-band setup is definitely much more expensive that the Ku-band one. But again, since most stations are here in Europe, that's a good way to feed the data. Regarding future DVB data streams, I have no doubts it's going to be like this for a long long while, there will be enough bitching about changing the dish from the old Met7 to the new setup, and by the time we will get the new MSG birds maybe everything will be on the Internet...
