I think I understand now. Thanks for taking the time to clarify your points. |

These satellites orbit at about 22,000 miles above the Earth.
As the Earth rotates, we have the day and night cycle as the Sun's position is fixed. The Satellites also pass in and out of the Earth's shadow.
If you can picture the earth from space, and imagine you're up by the Satellite, as the sun "Dawns" around the side of the planet, the sunlight will indeed be striking the satellite on the side facing the Earth, albeit at a bit of an angle, but it will be direct sunlight.
As the Satellite orbits, and the Sun stays fixed, at different times sunlight will be striking the satellite from the front, the side, or from behind.

Yes but the satellites are positioned over the equator, rotating along with the Earth, with their antennas pointed directly at the Earth. Since the Earth is in the way, it is impossible for the satellite to be hit with direct sunshine from the front.
At least that's the way I see it. If I'm missing something, by all means feel free to point it out. |

Heh. Um... I see what you're saying, ---but---
The Earth *rotates*. At different times during the Earth's rotation, all sides of the Satellite will be hit with direct sunshine. |

I said the antennas, not the whole satellite. Since the satellite's antennas are facing the Earth (duh), the sun is behind them. |

I wasn't even thinking about the satellites up in space, since the sun couldn't be hitting the antennas on those. I was thinking about the ground-based satellite dishes, which actually do get affected by the sun.
ROFL. ROFL!
Um. Excuse me. They are in Space. How can the Sunlight NOT hit them? Satellites are bombarded with solar radiation. They are engineered to try and protect themselves from it...

I think the ones out in space get affected by the sun as well. Since there was another news thread before about satellite bands and stuff I started reading up on it. It's a pretty neat subject.
A particular transponder could act up because of the way the sunlight hits it, knocking out that transponder for a couple seconds. Not for to long but it is possible.

This is true, but it only happens twice a year when the Sun for the few days it takes it to transit behind the orbits of the Geo Synchronous satellites. The outage will last for about 15 minutes or less. If they use this excuse
at any other time of the year they are feeding you a line

And this is because the sun is in the same position as the ground satelight, and the one in space, so what happens is the radiation from the sun hits the dish on the ground at the right angle, and interrupts the signal from space.

Most satellites use a combination of solar arrays and batteries to provide power (RTGs haven't found their way into common commercial use  ). It is difficult to transmit without power... |

Here's the list of things they've blaimed for the problem:
1. My TiVo
2. My TV
3. Sunlight hitting the satelite they get their programming from.
4. Wiring in my house (even though the problem shows up when I plug my TV into the drop)
5. Pretty much everything except themselves.
LOL @ #3, if sunlight were *not* hitting the satellites they would have huge problems, as there would be no power to beam anything anywhere. Sounds to me like total CS ineptitude.

LOL yipes, i've got 10 bucks that says this'll make their image worse, they cant redeem themselves in my eyes, i've already dealt with their crap cable and crap isp, about the pricing post...what about the GOOD package for them? DirecTV's good packages are pretty expensive, i'd still say they're better than comcast but 39.95 is sorta misleading because thats the craptacular package, secondly to morac OUCH, sunlight hittin their satellite???? didnt they plan for that? i mean satellites are outside arent they? lol, i feel for you man, why dont you go for anything else? stuff blocking your view of the sky? or just nothing available in the area? |
