Once you have your current position, then the program tells you where in the sky to look for the satellite. Elevation (from the horizon) and azimuth (direction from you). There are 3 WAAS satellites, 2 of which are for North America. As you can see in some locations, one of the satellites might well be below the horizon, and the other one fairly low, so it's quite easy to have your antenna too low and have the fuselage block the signal. In an ES it's not quite a bad because of the E glass instead of Carbon Fiber, but you still get some shading.=20 Since the WAAS satellites are geostationary, they are tipically lower on the horizon, and of course always SouthEast through SouthWest of here (anywhere in US).
