What causes Doppler shift within the signal in your theory then?

Atmospheric pressure. It's all magnetised.

Does an increase in pressure shorten or lengthen the wavelength?
Have you done any experiments to show the correlation between pressure and wavelength?

If not, how can you be sure there is a relationship?

I really don't know whether it shortens or lengthens wavelength, do you?

All I know is that nothing works on earth and I mean NOTHING, without atmospheric pressure/magnetism.

Where are the transmitters that satellite dishes point at? They all point at something over the equator.

Your equator is far far different from mine.

Maybe, but it is clear that the dishes point to a single transmitter high above ground level in the sky.

Dishes can point to one transmitter that is being relayed through another and another, etc as they are spread out around the concave earth. Come on man, it's not hard to understand how easily this can be done. You do not need so called satellites and never have or will.

So where is the transmitter that my satellite dish points at?

So just rambalings of a mad man/troll. Just as we thought.

A mad man and troll? Ramblings?
I'm simply telling you the truth. It's no concern of mine whether you accept it or not.

The dish on the side of a house receives TV signals. Where do they come from?  Aerials for terrestial TV come from a number of masts, but dishes point into the sky.

So if atmospheric preasure causes Doppler shift why does barometric preasure not interfear with the accuracy of the positioning signal?

My dish does not point into the sky, I can assure you of that. My dish is practically flush with my house wall, just like all the others in my area.
It depends on where you are located and to where any given transmitter is located as to how your dish is aligned to receive the signals which are coded scrambled signals, anyway, unlike the old TV aerials that simply pick up the closest signal to wherever the transmitter is situated without much fuss.

They aren't pointed at any sky at so called satellites, some 20 odd thousand miles out that supposedly keep a perfect geographical location with whatever part of earth they supposedly service and to think that these things have enough power to cover millions of homes, you have to be devoid, totally of any common sense or are still living in cloud cuckoo land and I'm being serious.

So if atmospheric preasure causes Doppler shift why does barometric preasure not interfear with the accuracy of the positioning signal?

How do you know it doesn't? If anything, it would be minimal in most cases unless there was a huge change in barometric pressure.
We see changes to lots of signals when there is a change in atmospheric pressures but they are usually minor unless the change is huge and immediate for a sustained period of time, in which case it would be catered for.

We know this because Doppler shift is a known constant with speed and does not randomly fluctuate with a given air preasure.

Well that's an absolute load of crap and you know it.

Try walking against the wind and shouting to someone 50 yards in front of you..see if they hear you clearly.
Now do it again and walk with the wind to your back and shout to the person in front of you.
This is the basics, Thaggy.

That's not what Doppler shift is. Do you have a clue about the topic? Or just making it up as you go along?

I'm making nothing up, I'm telling you how it is. Nothing changes in reality with the Doppler effect, it's simply down to what is PERCEIVED by any person.
For instance:
If a car is coming at you with it's horn blaring, you will hear it as faint and then stronger as the car approached you. There is no change in the horn strength in the car but there is a change where your ears are concerned in picking up the pressure effect from that travelling sound.
Radar works on the same principle. All you try to do is make a big song and dance about it all and try to make it appear more intricate than it actually is.

No it's louder because its closer. Lol

Doppler shift is a change in the frequency of the signal not the loudness lol.

Maybe one day you will be able to simplify your frequency and realise how it all simply ties in with what I said. Your head is full of silliness and way out mumbo jumbo to ever be able to use the simplicity of it all.
You have studied the Doppler effect  for a few days on the internet and you cannot stop yourself from going on and on and on about it at every available opportunity, believing that you actually know what you are talking about to the point of using it in SPACE you clown. 

So you have no explanation for it then? Apart from its all mumbojumbo?

There's nothing to explain. What are you trying to prove?

Trying to get an explanation for how the observable Doppler shift in GPS signals works in your backward world. Preferably on based in scientific reason and not delusional thoughts.

I'm probably in the minority, but I have been trying to make sense of any of sceptimatic's postings.

He seems to always deny the known scientific facts of just about any subject and make up some weird something or another of his own. I am also not sure if he is the "big hoax" or the "big joke" of The Flat Earth Society Forum  in that statement that someone once made that "The Flat Earth Society Forum is one big hoax or one big joke."

There seem to be plenty of sources for explanations of the Doppler Effect. This one, for example.:
http://www.acs.psu.edu/drussell/Demos/doppler/doppler.html
Seems fairly straightforward to me.

And since it is you claim that everything on earth works on atmospheric pressure and magnetism, it is your responsibility to prove it.  Otherwise we will just be accepting what we are told and being sheep.  Something that you claim we are already doing by not accepting your wild. Claims.

I'm not arguing the Doppler effect in earth's atmosphere. I accept it.
Now try it again, with SPACE.
Oh and remember...you need a MEDIUM, so chew on that for a little bit.

I can't directly prove anything to you, because your brain is only in neutral. Slip it into first and you have a chance of grasping logic.

Name me anything that does not use atmospheric pressure to function and tell me why it doesn't. If you can't, no problem.

You can't directly prove anything to me because you have not done any testing of your claims.  You claim that light and sound are the same thing.  Get off your ass and prove it.  You claim that what we percieve as gravity is caused by air pressure.  Get off your ass and prove it.  You claim the Doppler Shift is caused by air pressure.  Get off your ass and prove it.

Create some experiments.  Document what you are doing.  Take pictures, list steps, write conclusions.  Get off you ass and prove your claims.  It is that simple.

My dish does not point into the sky, I can assure you of that. My dish is practically flush with my house wall, just like all the others in my area.

Does it look a bit like this?



Because that's an offset dish, and although they look to be pointing horizontally, they are actually receiving a signal from a relatively high angle.



See? The 'apparent view' is where you think it's pointing, the 'actual view' is where it is actually pointing. Pretty simple stuff once you understand it.

I don't give a rats aris whether you accept/believe or deny it all. I'm only interested in those that want to at least try and work stuff out for themselves and you and many others do not come into that category, as your minds are already saturated in nonsense.

Yes, it looks exactly like this. So now they don't have to be angled because they can simply catch the signals now, even though just a slight movement would render them useless.
It's about time you realised that they are simply receivers from transmitters. Go and have a look around from the way your dish points, I'm sure you will find one.

It is because the way they are shaped.


Look at the Offset Feed image.  Looks like it is pointing down, but really it is pointing horizontal.

That is why. So why don't you take your own advice and open your mind.  Learn something.  Quit being so closed minded to your own theory.

No it's louder because its closer.

Doppler shift is a change in the frequency of the signal not the loudness lol.

It's obvious that sceptimatic's understanding of the Doppler effect and/or shift is very rudimentary.  And that's being polite.  As we (well, most of us LOL) know, the Doppler Effect is the shift in frequency and wavelength of waves which results from a sound source moving with respect to the medium.


In sceptimatic's example,  he's confusing the horn's decreasing proximity and its increasing loudness  with what he imagines the Doppler effect refers to.   He's also—apparently—not noticed the increased pitch of the sound as the vehicle moves away from him.

It's surprising, because even most high-school physics students are aware of this effect.

Show me some proofs about this Doppler shift in GPS signals and we can go from there.

Too easy.
 

Notice the compression of the sound's wavelength on the right of the front of the car.  To each of the listeners, the cars sound has a different pitch—caused by the Doppler Effect.
