Re: Eclipse - so they say

So, David, there are eclipses on MSG-1 too! :-)

Bye, Luca
Good to hear it doesn't defy the laws of gravity! Actually, there
was quite a good discussion in a recent RIG Journal about the effect
of eclipses. Spin stabilised satellites like Meteosat 7 and MSG are
not as efficient at collecting solar energy as 3D stabilised
satellites, where large solar panels can point permanently at the
sun. Consequently the loss of power around spring and autumn can be
more significant. MSG-1 has a power load 3 times that of Meteosat
7. The other effect is the sun creeping into the imager as
discussed.

Maybe if someone from Eumetsat is coming to the Utrecht meeting they
could bring some of those rather excellent purple booklets:
Applications of Meteosat Second Generation (EUM BR 11) which I am
sure people would find most interesting - hint, hint!

Cheers,
David
