Densely built urban areas tend to have the best cell phone coverage while sparsely populated rural areas tend to have spotty coverage.  That's pretty much the opposite situation of GPS having trouble in the "concrete canyons" of big cities and having little trouble in the wide open spaces of the country.

In the wide open spaces of the country, over the past years, GPS coverage as we are led to believe it is, has been widely inaccurate.
It's getting better by the day because more and more pretend satellites are being positioned in space to cater for it. When I say, pretend satellites, I mean transmitter towers and relays to cover the space on earth that are passed off as satellites.

If I was a billionaire, I would offer anyone one million pounds to directly prove to me that satellites are in space, knowing that my money is safe.

care to give us evidence to back up your statement of inaccuracy in the country side compared to urban centers?

I could tell you I had huge problems going to the west of Scotland using a sat nav which continually had me all over the place when I hit the sticks.
I could accept transmitters/relays/cells doing this but not a satellite in the sky Thaggy.
I also noticed when going to Scotland that my sat nav kept on re-adjusting. Maybe that was the satellite nodding off or something eh?

No, the satellites are working just fine.  It's your navigation system that's having the problem.  Sat nav gets positioning information from the GPS satellites, but it's at the mercy of the accuracy of its internal maps and routing algorithms for figuring out how to get you where you want to go.

oh and thork i also found a picture of a satellite in space taken from another satellite in orbit.

Is this your idea of a joke?

Are you seriously trying to say that this is a satellite?

you asked for a photo so i gave it to you. what were you expecting? a hd wrap around with perfect contrast and background lighting? its what would be expected from a photograph taken a few hundred miles away travailing at extremely different relative speeds. so no its not a joke its what you asked for. what were you expecting?

That's weird, I never remember typing that. In fact, looking at my previous post I only asked Thork how that is a joke.

That being said, I have no reason to believe it isn't.

When I asked for a photo to see what they looked like, I expected something like this.


Can you understand my bemusement when instead I am confronted with the picture below?

oh so my photos not good enough quality? how about these then?

That's lovely. Now can I see one of a GPS satellite and not of every other type of satellite that you can think of?

Honestly, that's laughable.
You expect there to be a picture of one from ~10 meters away in perfect HD etc? From what, another satellite?
How would they go about this? Attach a camera to a pole and take a selfie for this sole purpose?
That would be a dead giveaway of a conspiracy...

awwww are my photos proving you wrong not good enough for you?  lol.

so im glad you now accept that low earth orbit satellites exist, now suggest to me how you take a resolve of anything that small from 20,000 miles away?

http://upload.wikimedia.org/wikipedia/commons/1/17/Navstar.jpg

Here is one.

This is making me laugh.

Once one does fail, it's not clear how they get another one up there "pronto" to take up the exact position of the used one, so that we don;t need to alter our satellite dishes.

Rather than arguing from ignorance, why don't you take the same five minutes to educate yourself
as it took to post here? The geostationary satellites are not part of GPS.
The question is why do you have to point a dish at the sky to receive a signal supposedly from the ground?

And they do fail. They have backup control processors, and many TV satellites have suffered outages
due to positioning errors. We can send signals back to control them from the ground ya know!

Does it matter? If he can show you satellites that aren't GPS satellites, then surely GPS satellites can be up there too.

He didn't even suggest how we get a photo of a satellite 20,000 miles away. He never came back after that so I can assume he accepts he is wrong.

LORAN is based on line of sight beacons. That's a very flat earth technology if you ask me. Its not going to work so well on a round earth, is it?

This is true, you cannot use LORAN on the surface of the earth for an unlimited distance. You lose the signal due to the curvature of the earth.

Here is a simple experiment that anyone can do. Substitute "flat plane" for "ocean" if you need to, or just travel to the ocean.

I was at the coast where, at the top of a cliff where a lighthouse was built. From the beach, the vessel's superstructure could not be seen. However from the position of the lighthouse several meters higher, the vessel is visible.

Is there any way to debunk the fact that at one point in time a person at sea level cannot see a target on the horizon, but at that same moment, a person from a much higher vantage point CAN see the target. You can observe this for hours upon hours if the target is not moving, every day of the year, in any sea state (don't try your "ocean swell" bullshit on me)
