How do they work then?

What about google earth? I don't think they flew around the earth taking pictures.

GPS uses accurate clocks to triangulate position. It doesn't need satellites.

Google Earth buys pictures taken from aircraft surveys and arranges them on a 3D globe.

Planes have not covered the whole of the world mate.

Accurate clocks? Example?

Very true. Not with high resolution cameras at least. Which is exactly why rural and uninteresting places of Google Earth have low resolution.

Google mostly buys its aircraft pictures from geological surveyors.

Look up "how GPS works" on Google.

so why would they require an open sky? and list the satellites they are receiving their triangulated position from ?

It's listing the triangulating stations that it uses with its accurate clocks. Those triangulating stations can be ground based. The signals can be bounced off the atmosphere like radio. And the signals can also be broadcast from Stratellites. Lighter than air vehicles at very high altitudes.

Stratellite is a brand name (Stratellite is a trademark of Sanswire Network, LLC, which is a wholly owned subsidiary of GlobeTel Communications Corp.) for a proposed high-altitude stratospheric airship that would provide a stationary communications platform for various types of wireless signals currently carried by communications towers or satellites.[/b]

Key word there tom...proposed...

currently carried by...oh right...satellites..

good work tom!

Because the signals that are bounced off the atmosphere are rather weak. It works better with an open sky just like your radio works better with an open sky.

Stratellite GPS stations also require an open sky.

To date none of these designs have received approval from the FAA to fly in U.S. airspace.

GPS is Global Positioning System.  The transmitters do not have to be in space for it to work.

They fly in military airspace, at altitudes over 60,000 feet.

If engineers could make lighter than air vehicles back in WW2, then they could make remote controlled versions today.

A stratospheric airship is an airship designed to fly at very high altitudes (30,000 - 70,000 ft or 10 - 20 km). Most designs are (ROA/UAV) remote operated aircraft/unmanned aerial vehicles. To date none of these designs have received approval from the FAA to fly in U.S. airspace.

Tom...what has this got to do with satellites? Could wot?

Satellities do exists mate. Hence how google earth works and shows the earth to be quite round

I'm saying that Stratellites are what you think are Satellites.

Google Earth is simply a computer model of a sphere with aircraft pictures on it. It could just as easily be shaped into a flat earth. Or a square earth. Or a cylindrical earth.

Jesus christ. Why do satellities not exist? The technology is quite clearly there.

So where do all these NASA space missions fly off to then?

Satellites themselves could exist. They just couldn't orbit the earth due to its   lack of gravity.

Probably high into the atmosphere to deploy stratellites, or to conduct a survey mission or two.

Satellites require gravity to stay aloft.  No gravity, no satellites in orbit.

I jump....but then I fall to the ground. Without gravity? What would cause this effect?

Close. You jump, and the Earth rushes up to meet you.
