I tried ver 3 and it failed on my Vista laptop. I had to reinstall 2.76c.

I reinstalled all files and it runs ok except satellites. I put the txt files into a separate folder and specify it but it won't read them. In the calendar under satellites when I hit refresh I get a satellite file error. When I run the tle downloader I get the Run time error 76 path not found. No matter what I click on as a location or tle/txt type. I am downloading the txt from celestak manually then placing them in a folder. I can specify the folder with the tle downloader but it gives the run time 76.

Has anyone had this problem with 2.76c or know how to fix it?

I know I had satellites running before I tried 3 and went back to 2.76c.

I can't help you but I'm excited to learn it's possible to show satellites in Cartes du Ciel. When you solve your problem, please come back and tell us (me) how to do it.

The older 2.76c always had the feature. It's under the calendar feature. You needed several parts installed like calendar, TLE downloader and such. I had it working before I took it off but when I put it back on it's giving me trouble. I'll figure it out eventually. The newer 3.8 also will load satellite files under the calendar. It should already be installed. All you need to do is manually download the tle files and put them in the proper directory. William

Thanks; I had never actually used that calendar feature.

I must be really dumb but how do I do that, manually downloading a tle file? The space-track.org catalog files page shows two-line and three-line files, but they open in the browser. Do I need to actually copy/paste this into a text editor? And is it the two-line or three-line?

edit: OK I can save the webpage as a text document. How do I turn it into a tle file?

Change the file extension from .txt to .tle.

Unfortunately for me I still get the errors with my Vista laptop. I tried to save the satellite files as .txt and .tle in the same folders and still no luck. I'm not going to give up just yet. Or at least until I get a new laptop. My current one may end up under a sledge hammer any day. I had to do three hard shut downs in the last week. Laptop refused to close down and I had to remove the battery. I did get the satellite function working on my work computer which has Cartes 3.8 but is has Win7 and I can't access after work. William

Change the file extension from .txt to .tle.

I actually tried that, but it didn't appear to work. Windows Explorer stilled called it a Text file unlike the older tle files already in the folder as example. I couldn't get CDC to pick up that file either.

I'll have to play around with it a bit more.

I'm starting to think I'm better off just going to CalSky to find out about satellites.

Mark,

1. Does the file name show as, for example, "iridium.tle" not "iridium.txt"?

2. You are saying Windows Explorer shows the file as Type "Text Document" and not as Type "TLE File"?

Yes and Yes John.
I haven't actually tried again...
But I did double-check just now. I think the computer thinks this file is "satlist.tle.txt".

If that is the case, redo the file name and eliminate the ".txt" at the end. Make sure that the file extension is showing on files in Windows Explorer. [http://support.micro....com/kb/865219]

That trick worked; thanks John.
I can now
- download a TLE file (it doesn't seem to matter whether it's the 3-line or 2-line version ??) as a .txt document
- change the file from .txt to .tle and have Windows Explorer display it as such
- select the tle file in want in CDC
- click refresh to get the list of satellites shown (takes a long while though)
- click on the list of satellites to get them displayed on the sky chart.

The result then looks as attached. Is that what I'm supposed to see? I thought I would see the satellites slide over the chart in real time... :(

Apparently all it does is show the current path of the satellite. I tried the animation option but no satellites appeared. Also, once I started animation, I could not stop it.

Edit: OK figured out how to stop animation. You click on the same button used to start it.
