Re: Satellites : general discussion and musings

It becomes clear from studying those ionograms why refraction stops at normal incidence for radiowaves above 10MHz. For skywave propagation, it also tells us why the choice of incidence angle is so important. 10 MHz? The alleged so called satellite communications mainly use http://en.wikipedia.org/...

Re: Satellites : general discussion and musings

Dmitry, First, you are confusing arc with straight distance. We live on a sphere. http://www.femininebeauty.info/images/chord.arc.gif Of course, whatsgoingon. So what is your estimation for that chord length? With your input data, I've got 2 * r * sine (theta) = 2934 km. Am I confusing something? t...

http://www.myalbum.co.uk/GroteFoto-7HFBJH4K.jpg Where is a transmitter for New Zeland? Intelsat 8 is in the SAT TV offer over there. Supposing that communication satellites are real, the transmitter may be in Australia or somewhere in Asia -- i many places. As satellites never was presented as plai...

reichstag fireman,

You lowered your magic mirror again? Last time it was 600 km and now less than a half of it? But why?

Re: Satellites : general discussion and musings

The trig. I picked London/Greenwich to South-east Algeria, which we triangulate as the location of the Tx station. Tooway Satellite site shows this: http://en.toowaysat.com/faq.php http://i1260.photobucket.com/albums/ii567/888oct888/london-map.png Note the elevation (30 deg) and azimuth (168 deg) a...

Re: Satellites : general discussion and musings

To Astra is 24,4 I was thinking about Eutelsat which is 28,9 deg. according to satellite finder and that is how they point http://www.myalbum.co.uk/GroteFoto-IDNJRPSJ.jpg My question is why? I think it should be 80 deg. to point satellite. Please note that photographed dishes are off-axis (http://e...

Re: Satellites : general discussion and musings

Dmitry, You must be blind. Why are all the lines intersecting in Algeria? Any thoughts on that or are you glossing over my clue? I will get to your trig in due course, but you did not provide a diagram at all. This is the only way to communicate trig. You know that. whatsgoingon, Is it OK with your...

Re: Satellites : general discussion and musings

I briefly looked at Dmitry 's proof through trigonometry, and sfaics, he is correct for what he describes, although I fancy he's refracting(!) us from the truth! However there are other issues as well, aside those two points above.. What do you call truth there? That one can see Madagascar from Lon...

Re: Satellites : general discussion and musings

how about a tiny school trigonometry problem? You need to draw a diagram and upload it at this point. I will do the trig myself given the Tooway Satellite internet information I found which gives precise azimuth and elevation angles to use. I wait with an enormous interest, whatsgoingon. Please pub...

Re: Satellites : general discussion and musings

Simon, A: As far as I know ..., you can't apply thrust in a vacuum. This sounds very bizarre to me. Could you please point any source of that knowledge? Or name some law of physics in question. I really wonder what to explain here. B: Likewise, how did the SYNCOM's propel itself in any given directi...
