Astra 2F at 28.2E: General Discussion

[PaulR]

That's going to be true. We've always said that there will be minor differences in the fringe areas, that gives some depth to the statements.

 

[Lazarus]

Very wise comment, I thought

it seems 2Fs beams moved to the southeast a bit. The NULL has moved further out.
At noon i've measured the highest ever SNR. It increased a bit more than 2db compared with last weeks values. From others i read similar reports. People living on the other side of the NULL report the opposite, weak to no receiption during noon.
From my calculations i can deduce that the beam moved about 20km.



Look at the light blue line:



Any new rumours ?

or cold weather? You have -1 C.

Nope. The Null moved. Otherwise the people on the other side of the null wouldn't report what they report.

 

[peeter3000]

I will check tomorrow morning with my tbs5922.

probably too late now. You've missed the happening ;)

Yea....2f uk beam signal coming in really strong today 100Q all day dropping only to 80Q in the evening....its as if SES pressed the "turbo boost button ".... :-) .....

 

[cazhh]

still high this morning:

 

[peeter3000]

direction of 2F was yesterday evening 28,17E

 

[Steve Steve]

All 2F UK.....(even tho its raining).....still coming in here at a "Turbo charged"....100Q.........It won't last tho.......

You never know ...

Yes, I'm east of the first null. Very low signals at noon during the last days (also at other times). I see that when the null is moving closer to me, the daily variations also increase...

It happened before, 29.10.2013, same Peak round dinnertime.

Cazhh....you know it won't last ...after over a year experiencing 2F reception it will go ( In my case)...from 100Q------to 50Q....for no reason...that's how it is.....

Noon in Munich is always max signal ..730- 1100 pm low signal...

 

[smoggy07]

They might have shifted it a touch to make room for 2E

Same here, but you are still lucky. I am 200km due North (A9) and I Need a 240cm to have 24/7 reception. Although I have not experienced the "spring low" yet.

position of the satellite inside the box is not related to the location of the beam. Attitude is controlled independently. While "moving" the satellite around can have an influcence on the attitude it shouldn't and my data shows no correlation between boxkeeping manourvers and beam location.

 

[cazhh]

I've took one of bema's graph and flipped it vertically. Then adjusted the starttime of the graph (mine start at 00:00, bemas at 19:00).
This is the result:



If you compare it with mine you see that it matches almost 100%. After flipping.
There can't be any better proove that the variations during the day are caused by the beam moving over the earth.

 

[Huevos]

Agreed. A 0.1º shift at satellite altitude is roughly 12km, which equates to about a 2km shift of the footprint at ground level.
