How do I cancel service?

Hello,

I am wondering how to cancel my service with Hughesnet. We own our equipment, it's not leased or anything. We are just moving and have found a better choice in internet and have no interest in ever having Hughesnet again. Do I need to send the equipment back? How bad will cancellation fees be? (We haven't signed anything since our two year contract when we got it.. like years ago. Haha.) Thanks for the help! :)
