Because sustain space flight is impossible maybe?

If satellites do not exist, then why should I be expected to post true pictures of the Earth?
So it's an 'if'?

A satellite orbits the Earth, just in case you didn't know.

So jroa has chosen not to answer another one of my questions—again.  This is becoming a habit mate LOL.

Can you explain—briefly—how GPS devices work so effectively if satellites don't exist?  Even away from the line of sight of earthbound transmitters—such as in canyons or caves or mine shafts.

How does FM radio work so effectively?  I will give you a hint.  It is not because of magical trashcans floating around the Earth.

But back to the real question. Why do you think anyone would want to tell lies about a satellite, hmm? Or, why do you think they are fake. You have to have reasons, you know.

FM radio is 100MHz, satellite tv is 11GHz.  Very different.  What has FM radio got to do with satellites?

And AGAIN jroa avoids addressing my GPS questions, and instead tries one of his favourite diversionary tactics—changing the subject.

jroa, you need to understand that—besides being totally irrelevant to my GPS question—FM radio has nothing to do with satellites. 

And talking about "magical trashcans" is starting to make you sound like a ten-year-old grade school kid LOL.

If FM radio signals can be transmitted by land based transmitters, then why not GPS radio signals?

Satellite signals operate at extremely high frequency.  This is necessary for the amount of data that is transmitted.  FM works great for low fidelity audio but doesn't cut it for HD video and such.

Higher the frequency, the less it can bend around corners.  Satellites require close to direct line of sight for this reason.

GPS requires three reference points to determine where you are. If it's all done through radio waves on Earth, then how is your position calculated when you're out at sea? Are there radios dotting the ocean so you can use GPS, and why bother making the system assume the world is a sphere?

A large amount of data?  It is a location and time stamp.  GPS is not sending the entire internet to you.  ::)

I was referring to Satellite dishes for TV.  But even then I simplified the story.  You can get local channels in high def from traditional broadcasting towers.

You are also right about GPS, as location can be done with ground towers.  Cell phone towers are used for this purpose to triangulate a location when GPS is disabled or not present on that particular device.

In light of this I should do more research on why satellites are preferred to ground based transmission at lower frequency.  I suspect it is an economic issue, as a single satellite would have the coverage of hundreds of towers.

WWVB is a very interesting radio station. It has high transmitter power (50,000 watts), a very efficient antenna and an extremely low frequency (60,000 Hz). For comparison, a typical AM radio station broadcasts at a frequency of 1,000,000 Hz. The combination of high power and low frequency gives the radio waves from WWVB a lot of bounce, and this single station can therefore cover all of the continental United States plus much of Canada and Central America as well …

The coverage map looks like this:




So this single transmitter can be received well into the Pacific and Atlantic oceans as well as parts of Canada, Central America and even part of South America.

It would seem to me that it would only take maybe a dozen or so of such transmitters to cover the entire plant.

In fact, WWV can indeed cover the globe when propagation is good enough. Just like a GPS satellite, it constantly broadcasts the time, and it seems possible that one could use its signals in precisely the same way as one uses GPS to determine one's location, given several signals. There is a rub, though - WWV broadcasts in the high frequency part of the radio spectrum (1.8-30 MHZ is HF) which is subject to ever changing and anomalous propagation.

GPS operates in the gigahertz range, which is not subject to this kind of anomalous propagation. It is more or less strictly line of sight, perhaps bouncing off raindrops and snowflakes by by and large going in a straight line, unlike HF signals which bend when the encounter the ionosphere (or the giant crystalline orb inside the hollow earth in which we live which contains all of "space").
