I know that this subject comes up a lot, but i"ue been seeing what i can find on the internet, and am pleasantly surprised that other people haue their suspicions, too.
I found a 35 page thread on the "September Clues Research Forum" all about this subject.
This post, by "Farceualue", i thought was pretty interesting:-
"I have been researching GPS and how satellites are said

The document you posted has an awful name: ignorance.
It is entirely based on:
"I can't understand how that thing works, so the only conclusion is it doesn't exist."
But ignorance has a huge advantage over knowledge: it spares you many headaches. Sad but true.
Read the link provided by markjo, it is a good starting point. Note that the first GPS satellite got in space in 1978 (!!!).
Meditate about how many engineers / physicists / scientists / astronomers / mathematicians got involved in designing / constructing / sending in space / receiving data / analyzing data from 1978 on.
Meditate about how many people in all the world use GPS day in and day out from 1978 on.
Meditate that GPS works even in the middle of the ocean, if anything, it is just in the middle of the ocean that GPS is the only kind of localization that works.
I presume you can meditate about all this (hint: mom made you a brain).
And then answer this question: is it possible that it's all a scam, that orbiting satellites don't exist, that all those persons involved in GPS was mistaken about the shape of the Earth and/or enrolled in the Conspiracy?
Needless to say, for our friends Fe'ers that pile of rubbish is "a good source".
Oh yeah, let's go on fellows. We have to spread the Word.
