Hi all, Where may I find (who can provide me with) a ready-to-use formula giving : . for any terrestrial site and at any time, . the altitude of the Earth shadow as a function of a satellite position in the sky (height, azimuth ; or else, R.A. declination) ? If possible, accounting also for penumbra-umbra would help. Thanks in advance Alain Figer -------------- next part -------------- An HTML attachment was scrubbed...
