Not at the same angular velocity as GPS satellites.

GPS 'satellites' are geostationary, or nearly so. They don't streak across the GPS screen.

*sigh*  No, Tom.
Quote from: http://www.kowoma.de/en/gps/orbits.htm
The satellites orbit the earth with a speed of 3.9 km per second and have a circulation time of 12 h sidereal time, corresponding to 11 h 58 min earth time. This means that the same satellite reaches a certain position about 4 minutes earlier each day. The mean distance from the middle of the earth is 26560 km. With a mean earth radius of 6360 km, the height of the orbits is then about 20200 km. Orbits in this height are referred to as MEO – medium earth orbit. In comparison, geostationary satellites like ASTRA or Meteosat – satellites orbit the earth at 42300 km, which is about twice the distance of GPS satellites.

The satellites are arranged on 6 planes, each of them containing at least 4 slots where satellites can be arranged equidistantly. Today, typically more than 24 satellites orbit the earth, improving the availability of the system. The inclination angle of the planes towards the equator is 55°, the planes are rotated in the equatorial plane by 60° against each other. This means that the orbits range from 55° north to 55° degrees south. Block I satellites had an inclination of 63° against the equator.

I don't know. Sounds nearly geostationary to me.

You're kidding, right Tom?  Geostationary is a 24 hour orbital period over the same spot above the equator.  A 12 hour orbital period inclined 56 degrees to the equator is not even close to geostationary.  ::)

Actually the article says that the satellite moves with a "circulation time of 12 h sidereal time, corresponding to 11 h 58 min earth time"

Ergo, when the earth moves 11:58 hours, the satellite has moved 12 hours.

Ergo, when the earth moves 23:56 hours, the satellite has moved 24 hours.

The satellite is following closely with the Round Earth's rotation, nearly matching it with a difference of four minutes, as the article also mentions.

GPS satellites don't streak across the sky as you are imaging. Their movement is nearly imperceptible. They are nearly stationary. When you watch the GPS locations on a GPS device they are entirely still, with slight movement occurring only over a long period of time.

Tom, 12 hour orbital period means 2 orbits per 24 hour day.  That's twice around the earth every day.  How is that nearly imperceptible?  ???

Quoted for sheer ridiculousness.

Dude. Earth is a massive spherical object floating in a giant sea of absolutely nothing known as space. I can go on and get more evidence of the curvature of the earth if you like...

Hey, comon.

GPS can be conducted with the use of: aircraft up in the air, fixed anntennas, stratellites.

GPS "sattelites" are geostationary, that's what russian wikipedia says - we are always simplify things :) Moreover, Tom stated the same geostationary thing.

And that links with the tour on the ISS - what they for?
Give us a video where he is taking it from the inside, then steps to the window, show us earth, then show us sun and moon, how it might be seen from the orbit. And please, make it rather long, so we don't think this is computer movie, in the Avatar style.
Why the fcuk he didn't show us moon and sun from the illuminator? What he is doing I've seen in the computer game Duke Nukem 3d ten years ago.

Sorry, may be it looks like trolling, but you are just mean guys!

Umm...  No.  Neither the American GPS, the Russian GLONASS nor the European Galileo satellites use geostationary orbits.

If so that means all programmers for GPS would be in on the conspiracy and a lot of people in all armies.

Love the way he says Satellites are probably crap. Yeah, probably, well done with your whole Flat Earth Theory and your certainty over the matter.

Tom proves once again why we should believe anything he says.

Not really, no.


Good job at destroying any credibility this theory had because you struggle to understand simple things.
