You pick up satellite TV with a parabolic dish that points at one spot in the sky where the geostationary satellite lives. A sun outage happens when the sun wanders into the focus and overloads the receiver with noise that drowns out the satellite signal (at least, it raises the noise floor enough that you can't receive the high bitrates needed for a TV picture).
You pick up GPS with a whole-sky antenna that receives signals from the constantly-moving swarm of GPS satellites. It undoubtedly receives some noise from the sun, but the only factor in how much of that you get is the sun's elevation above the horizon. It's not really relevant whether the sun is "aligned with a satellite" or not. Even if it was, the satellite would be somewhere else a minute later. :) Andrew On Thu, Oct 9, 2014 at 1:40 PM, Bob Stewart <[email protected]> wrote: > Two days this week, there was a 3 or 4 minute outage on DirecTV as the sun > aligned with the satellite and my dish.
