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.

Subject: [MSG-1] Eclipse periods
Will MSG-1 have eclipse periods like other geostationary satellites,Interesting point, David. 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.
