If you arriving at terminal one, the "satellite terminal" is a small terminal for US flights (Dash-8 and small RJ type planes). You will have to get on a bus which will take you to the main terminal - about a 5 minute ride or so.

Can't comment if you will have to go through customs or not before your next flight. They will announce it on the shuttle bus however - I have just never paid attention.

At the satelite terminal you get forced on a bus so you will have to search out concessions at the main Terminal 1 (there is only a small coffee shop at the sateliete terminal anyways).
