Re: Using DE441 ephemerides

you should avoid using the "_" character in object names. I think it is misinterpreted. Am I allowed to use spaces instead, then? Or should it just be CamelCase? That is, would it be better to say "Mars Barycenter" or "MarsBarycenter"? Though for that I was mostly just...

Re: Using DE441 ephemerides

For future reference/help for someone else coming through here later who might want to do similar, this is my SSC file: ## ## MERCURY ## ReferencePoint "Mercury_bary" "Sol" { Beginning "-13201 05 06 00:00:00.000" Ending "17191 03 15 00:00:00.000" OrbitFrame { ...

Re: Using DE441 ephemerides

AHA! After several hours of fiddling and hacking and trying different things, I think I have found the problem. In my SSC defining all the things, I had Origin wrong; it should be the other number on the brief line, not the same as target. So for instance I had Earth with an Origin of "3" ...

Re: Using DE441 ephemerides

Ah, I didn't realize that SSC also had things for replacing Earth; for some reason, I thought just setting the barycenter's orbit would do the job. So, I did that—modifying Earth—and it's now kind of screwed up. Here is the relevant part of the SSC: ## ## EARTH ## ReferencePoint "Earth_bary&quo...

Re: Using DE441 ephemerides

you did edit my ssc file to use the 441 kernel? To the best of my knowledge, yes, plus the additional thing for Earth relative to Earth barycenter per onetwothree's comment. Here is the full text of the SSC file as it currently stands: ReferencePoint "Mercury_bary" "Sol" { Begin...

Re: Using DE441 ephemerides

Ah, it would seem that with the console open, if I hit Enter, I can then use arrow keys to navigate it. I did not realize that! Anyways, now, scrolling through, it does look like it's loading the SPK file extras/SpiceSolarSystem/data/de441.bsp It then gives me the error: Error in .ssc file (line 170...

Re: Using DE441 ephemerides

I made changes to /Applications/Celestia.app/Contents/Resources/CelestiaResources/celestia.cfg I changed the line from # LogSize 1000 (so commented out, so it should have just used the default of 200?) to LogSize 20000 To no avail. I find it weird because the comment says the default log size is 200...

Re: Using DE441 ephemerides

1) Open console (press ~) and check if your file is loaded correctly. It looks like the console only keeps the last 10 messages or so, and by the time I can hit ~ to open it the first half of mine is things like: - Failed loading Sol2Box - Failed loading Sol3Box - Failed loading Sol4Box etc. Is the...

Using DE441 ephemerides

Hi everyone! I know I'm new here, but I've been trying to do something with Celestia for a while now and I've kind of reached the end of what I can figure out on my own. I am running Celestia Version 1.6.3 (5) on macOS Ventura 13.4.1 (22F82) on a 2023-model MacBook Pro with the Apple M2 Pro. I am in...
