Ooops! I forgot to say that the file is satill.zip on my website
www.g3vwv.co.uk
It's on the OSCAR-11 page and the general satellite page.

Hi Norm,
I did this many years ago for OSCAR-11, and published an outline of the
procedure in OSCAR News.
The calculations were based on procedures written by James Miller G3RUH.
There is a package of files which includes the software, documentation
and original G3RUH articles. It's a long time ago since I did this, but
IIRC there is a spread sheet graph which compares the eclipse prediction
with the solar array currents.

Hi all!!
How does one calculate the period and time of entry and exit of eclipse?
I'm going to be helping a friend do an Arissat presentation for her
class. Due to the fact of the battery failing, this gives a 15 minute
hold before the power management allows transmission. So, for any
chance of receiving the bird, it has to be in sunlight for 15 minutes
(or so).
I'd prefer a mathematical formula. Echo goes through some of the same
trials.
Thanks,
Norm
BTW: I am an engineering student, just throw the math my way.
