Hi all, 1 or 2 degree per second is an educated guess for almost all passes. If the pass is over head the speed will increase up to 4/5 degree per second (as maximum value), such a speed is not achievable by all rotators. Hope that helps, 73s Fabio IZ5XRC www.amsat.it On Mon, May 13, 2013

One needs to also realize duration. The time say above 70 degree elevation (where rates are highest) are less than 2% of the total pass times. Not worth worrying about. Similarly, a LEO satellite spends 70% of its time below about 22 degrees. (but it is far away and needs max gain). So simply
