Using the framework developed for showing where Hubble is now, I have taken a snapshot of all the satellites orbiting planet earth.
Attached is the kml that show their position and height over Earth as of a few weeks ago.
For a real cool effect, simply rotate the earth!

And here are the debris!

Very, very COOL. Thanks.

A good way to see satellites in real time is still
Some years old, now, but still impressive.

J-Track 3-D is great and I do like it. The distinction here is that the second kml referred to here tracks space debris, which includes inactive satellites and junk in orbit. This is a rising concern especially after the recent satellite collision.

For satellite dish aiming, maybe this should be a plug-in to Google Sky:
As direct satellite transceiving becomes more available to consumers living mobile, living in remote areas, or just being satellite channel surfers, a droid app to facilitate dish aiming would be extremely useful to dish owners.
I would envision the app would
- attach to dish via a device that would orient the droid as needed, maybe along the transceiving axis of the dish
- calculate droid location and orientation from GPS, etc.
- USB interface to control aiming servo motors and to remotely display virtual sky scene with all known birds and with a crosshair+tolerance circle/box in the center showing real time where dish is aimed.
- access web to keep its internal list of birds current
There are many retired people living mobile, many traveling show groups, off-the-grid remote homesteads and communities, marine-based groups whose communication needs urgently require satellite communication. The availability of this app would allow these and their wannabe's to affordably aim their dishes as needed.
This exact same app would also help telescope viewers to find satellites to observe.

Thanks! Pardon my lack of knowledge but out of curiosity, are the satellites that are a significant distance away from earth intentionally placed there or did they stray away?

I'm certainly no expert (not a rocket scientist!), but I know that different satellites are placed at different orbital altitudes for different purposes. And I also know that there is a relationship between orbital altitude and orbital period. For example, the Moon is a satellite which orbits the Earth at a distance of about a quarter of a million miles, and takes 28 days or so to complete that orbit. Coming in closer, the GEOSYNCHRONOUS ORBIT distance is 26,199 miles, and the period, of course, is 24 hours. Equatorial geosynchronous orbits are used, typically, for data, television, and communications purposes, because the satellite appears to stay in the same place in the sky at all times to ground-based observers. This means that you can point your satellite dish at one place in the sky, and the satellite signal will remain constant. The orbital period decreases until at a low earth orbit of, say, 250 or 300 miles or so, the period is in the ballpark of 90 minutes. Among other reasons, one reason to use low earth orbits is because it takes less energy to achieve a lower orbit than it does to achieve a higher orbit. If you simply wanted to send a human being up in space, from an energy perspective, the lower the better, as long as it was in a stable orbit.
SATELLITE orbits can take on a variety of inclinations and eccentricities, too, again, depending upon the purpose or mission of the satellite.
Good luck, and have fun!

Can you please tell me why all your markers are showing up in the GE earth browser? I don't recall installing your "Satellitesinorbit" collection and can't find it anywhere in my GE database, but all your tracking info shows up all over the map. Shouldn't this be visible only in the Sky browser? Is there any way to remove it from my browser?
|Re: Satellites in orbit||tesseracat||4/8/12 7:39 AM|
Same problem as Zenomorpff here. Please help!
|Re: Satellites in orbit||Hill||4/8/12 11:09 AM|
This is a temporary problem caused by transition from the old GEC community forum to the present forum structure. It will eventually get sorted out.
|Re: Satellites in orbit||VariForm Zaftig||4/22/12 8:59 AM|
time to remove the entire Satellites in orbit group... I too am irritated by satellite markers which have become earth Junk...
|Re: Satellites in orbit||cregil||6/6/12 7:23 AM|
Aha! So it is not just me? Then I will stop trying to find how to turn it off!
I keep bumping into these things, and while I enjoy astronomy and space, I never expect to look down to learn anything.
