Celestia Forums

At the Motherload website I looked for the add-on for the Earth's latitude and longitude but came up empty. Can someone direct me to that resource? I didn't see it as something that I can simply display with the click of the mouse so I assume I have to download it. I am most interested in the equato...

I used Grant Hutchison's, July 2003 CONVERSION OF NORAD TWO-LINE ELEMENT FORMAT TO A CELESTIA EARTH-ORBIT DEFINITION spread sheet to plot the current position of the Space Station. It seems to display the current position in longitude fairly accurately but was about 500 miles too far south in latitu...

Here's a picture of Celestia displaying satellite orbits and the Earth's axis and coordinate grid: http://www.lepp.cornell.edu/~seb/celestia/images/satellite-orbits.jpeg . Can someone tell me the shortcut keys to display the satellite (spacecraft) tracks? Also, is it possible to set the time to wha...

I spent about 10 hours a day for a month learning about satellite orbits and coming up with my own ideas on how to have my students see for themselves what inclination means and what eccentricity is along with the differences between low Earth, intermediate Earth, Molniya orbits and geocentric orbit...

Here's a picture of Celestia displaying satellite orbits and the Earth's axis and coordinate grid: http://www.lepp.cornell.edu/~seb/celestia/images/satellite-orbits.jpeg . Did you use "Grant Hutchison's Spreadsheets" to make the traces that you have here? I'm sure I can figure this out eventually b...

Thanks for the replies.

The type of inclination that I am looking for is exemplified in this graphic.

I am aware of various web based satellite tracking programs and shareware. Celestia I was hoping might work to demonstrate certain orbital parameters like inclination. As far as using it to make predictions, I don't need it for that. I usually use Heavens-Above. I would like to show some animations ...

Hello, I'm trying to find user friendly planetarium software that we can afford to install on multiple computers at the small school where I teach. What I really want it for is to make manmade satellite predictions for curriculum I'm writing for my graduate degree. I need to see the tracks as well a...
