As part of a network simulation I am building, I need to display a map with pretty little satellite images moving around it, with the network connections forming and breaking as the sat's change relative positions (guess who wants this toy ;-) Given some simple stat's about a sat, I need to know its position as time changes, the set of other sats that it can "see" (ie, not blocked by earth), and the regions of the ground it can see. As a student at a University that does not require its Computer Science students to take serious Physics, I would be most comfortable with a canned collection of formulae I could use to build a "satellite ADT" that given the orbit and the time, would give me the relevant info. It seems to me that both the home SAT TV bunch and the HAM SAT people would need something like this, so there should be existing books or programs.
