Good day all,
Some time ago I read a very interesting posting or article by someone who had performed some analysis on elevation angles for satellite passes grouping them into degree ranges and percentages of passes. I recall it was a way of showing that most passes will occur within certain elevation ranges.
For the life of me I cannot who it was who had done this analysis or where I saw it and I just don't seem to able to ask google the right question to find it.
Can anyone point me in the right direction?
cheers, Graham ve3gtc
