Updating ISS Position

[Chuft-Captain]

1) Can I edit the text files in WordPad? The Notepad does not put neatly the text.

Yes. You can also use NOTEPAD++ which is a more fully featured editor, yet still free. (Easily found with Google)

2) Does ISS parameters change often ?[/color]

In real life, constantly. In Celestia, not so often.

You'll need to edit Celestia's SSC catalog for the ISS.
If you're running Celestia v1.6.0, that file is
Celestia\extras-standard\iss\iss.ssc

It's a plain text file.
If you're running Windows, please take a look at
http://www.lepp.cornell.edu/~seb/celest ... html#2.1.1
That section of the Web page describes some of the issues related to editing under Windows:
a. you can use Notepad to edit Celestia's catalog files
b. you'll need to disable "hide known file types"
c. you should associate .SSC, STC and DSC with the Notepad editor.

http://www.lepp.cornell.edu/~seb/celest ... eters.html
describes the standard names for orbital parameters and their equivalent Celestia parameter names.

Documentation of SSC catalog files are on the documentation page on the MotherLode at
http://www.celestiamotherlode.net/catal ... ation.html
and in the Celestia WikiBook at
http://en.wikibooks.org/wiki/Celestia/SSC_File

Does this help?

I regret to say that your course of action is beyond my competence. Is there a file somewhere where these parameters are already done?

Thanks.
