Just as a curious side point... last night I was thinking about the moon and its effect on the earth (tides, etc.) and wondered just how much does it affect the orbit of a satellite such as D11. Getting online this morning, I did a quick search of this thread and saw a few comments that refer to this, but I didn't find anything that says how much of an effect it is.
Is this something that needs to be routinely corrected every 28 or 14 days, or are DBS allowed to drift because of lunar and other gravitational forces, drag, solar wind(?), and other cumulative errors until such time that a correction has to be made? Perhaps these effects are so small that there are no routine adjustments and they're just done as needed.
Are there actually rules that define how far a satellite may drift before the FCC step in with a warning, or does it never even come close to that - presumably because there would simply be a customer outcry due to poor reception before that would occur?
Hey guys - once again, as with D10, this thread is a fascinating read - many thanks to the people that really take the time explaining this (we all know who they are!).
What does this question have to do with 780p vs. 1080i resolution? Stay on topic!
Seriously, I was hoping for an informed response to this question. thx
