AGI are the folks who make and sell STK (Satellite Took Kit, I believe)
which has a dominant position in the marketplace for doing analyses of
satellite orbits, visibility, planning, etc. They have all sorts of
hooks for their product: antenna patterns, link calculations, etc.
I prefer SOAP (Satellite Orbit Analysis Program) from Aerospace
Corporation (free for government use, maybe even for non-profits), but
STK is a much, much bigger commercial player.
Both products have fairly steep learning curves.
