There was not a specific bird for that system. You literally had a handful of satellites to choose from depending on los. Do I remember the birds?.?...Sorry but it has been 10 yrs and I've slept since then.
Your best shot is to eyeball where it is pointing with a properly calibrated compass. Each antenna configuration could be associated with multiple satellite locations but there is only one slot associated with your account.
If it has moved for some reason, you'll need to have it re-pointed as aiming is not normally an customer level task.
