Both satellites are at 99W. But it's not as simple as you might think. First, you'll need a proprietary antenna pointing aid (APA). Then determine the RF polarization of the TRIA; RHCP or LHCP. That determines which of the two satellites is accessed. Then you have to arrange for Wildblue to put the account on that particular satellite. At that point they'll give you a filter setting number. You set the APA to that number, which will then discriminate the specified sub-carrier on your assigned cell.
