GPS works on frequencies between 1,100 and 1,600 MHz. At these frequencies, the penetration depth of the electromagnetic waves in seawater is between 1.4 and 1.7 inches. This is a very inefficient way of communicating with submarines. I call your point moot.

Strats?


GPS needs satellites to function or an unbelievable amount of towers. Also why does my boats gps work in the middle of the ocean? There are no towers around. Also don't say a fleet of high flying planes as that requires a very large amount of people, fuel, and money.

It's entirely reliable for near-surface navigation.

Still haven't given example of how GPS would work without satellites.

It's been done to death in numerous threads here.  I'm not keen on covering gone-over ground.  Maybe someone else feels fresher.  Apologies for my ennui.

Look up some threads covering 'stratellites.'  I really do apologize, I'm sort of busy today storing away the Christmas stuff and sweeping out cedar needles.

stratellites are basically the planes I was talking about. They would show up on radar and such for regular planes, would require maintenance and fuel, and would have to be everywhere to give adequate gps coverage. They are not feasible at all.

No, it isn't. Subs don't travel 1 inch below the surface of water. That is effectively a ship. You know nothing about submarine navigation, so please stop making up stuff as you go along.

Or as submariners would call it 'a boat' but hey, call it what you like. GPS would still be reliable at periscope depth, would it not? Essentially antenna depth.  I did not say or imply that submarines used GPS at depth; or that it took the place of Loran or whatever.   

And what you are effectively saying is that subnarines aren't equipped with GPS equipment?  You're absolutely right, I would never have guessed that.

A reference, as requested, for Parsec (and please remember I said the very early days of GPS):

 
"The TRANSIT system, also known as NAVSAT (for Navy Navigation Satellite System), was the first satellite navigation system to be used operationally. The system was primarily used by the US Navy to provide accurate location information to ballistic missile submarines, and was also used as a general navigation system by the Navy, as well as hydrographic and geodetic surveying."

From: http://en.wikipedia.org/wiki/Transit_(satellite)

Still doesn't work in FE. Give me a better reason that psuedo or stratolittes. I already debunked those 2.

If you read the thread, it would be helpful. Would require many, many, blimps/airplanes. This requires fuel, people, maintenance, and would not be as effective as gps really is.

You are supposing/assuming a spherical earth.  Rethink it on a flat surface. 

Re: NASA update: more ridiculousness

Doesn't change anything. Radar still works, Planes need fuel and maintenance, and they still need to be around in large numbers (easily noticeable numbers). Just less than a RE.

Think next time before you post.

Weather balloons don't show up on radar. Why would a stratellite at the edge of the atmosphere?

Actually, a stratellite is not a plane. It's a helium balloon. And last I read, a stratellite only needs maintenance once every 24 months.

Quote

Why? Because their range is limited by the curvature of the earth?

You're forgetting that the earth is flat.

Why do they stay still (necessary for gps or we need to know where they are going)? Who made these balloons? This adds a lot of people to the conspiracy.

Also, one of these balloons has never failed and fallen to Earth?

NASA has admitted that they have $500-a-pop pseudolites. They might as well be disposable.

Stratellites are able to remain in stable position with solar-powered electric motors.

Solar panels are expensive.

Also people have to launch these with all this stuff. One person can't do it. Also every country when then need to be in on the conspiracy. You can't chalk everything up to conspiracy you know.


Also how far do you believe the atmosphere to go?


Off Topic: What do FE'ers think of affordable space travel? When it becomes affordable/safe, will you believe it or go on it? Would it prove to you the curvature or lack thereof of the earth?

I think I'm safe in saying solar panels are cheaper than satellite launches.

Re: NASA update: more ridiculousness
« Reply #55 on: December 27, 2009, 03:57:00 PM »
So what?

Basically FE thought is, earth is flat thus nasa is wrong thus earth is flat.

Also wouldn't people wonder why Nasa designed a psuedolite? And is buying tons of solar panels and motors? Conspiracy would have to be about 20 people before someone leaks for money.

The Air Force makes the claim that the latest IIR-21 was launched by the Air Force at Cape Canaveral Air Force Station, Florida.  But that's okay if you choose not to believe it.

NASA has still launched GPS sats so it doesn't matter. They must be in on it. Good try though.
