spice2xyzv.exe error: "SPK type 21 unsupported"

[EarthMoon]

Where can I download the Windows binaries for spice2xyzv?

[pedro_jg]

The Wayback Machine has an archived copy, which can be directly downloaded from http://web.archive.org/web/20120426100524/http:// ... /celestia/files/spice2xyzv.zip

speaking of this, I really should get to finish some of my trajectory conversions...

[EarthMoon]

Is there also a documentation/readme for it?

[pedro_jg]

The tool's readme can be found along its source code on Celestia's GitHub repository. There's also some example config files, and a leap second kernel to be put within the same directory as the binary.

I did everything the readme.txt says. It now gives me an error when I try to run a test (with comet 81P/Wild 2)

Error:

SPK type 21 is not supported in your version of the SPICE library. You will

contain this SPK data type.

Celestia's log also shows the error "SPK 21 not supported" when I try to run the .bsp file with Celestia.

SPICE .bsp file source: Generated with JPL's Horizons system
Config .cfg file source: Self-made
Output .xyzv (failed) source: spice2xyzv.exe

Here the files that I'm trying to run (Spice kernel, config & failed output):

[pedro_jg]

I can indeed reproduce this error using the files you provided (which is news for me since I've never used .bsp files from Horizons before). One solution might be to use a newer version of spice2xyzv. There's an archived copy of the Bintray files which were once used to distribute Celestia builds and such, it can be found here. Look for one of the celestia-tools packages (either win32 or win64) and then for the matching celestia-bin package, which contains Spice.dll, needed to run this newer version.

The resulting output then is:

We're going to need a kernel that includes data for the Sun, such as de440s.bsp from here, After editing the .cfg file to refer to it, also changing the observer to 10 (Sun), the result is a fully working .xyzv file.

I did what you said, but now it gives this error:

I don't have the spice2xyzv in "C:/Program Files/celestia/share/celestia/spice2xyzv.exe", but it looks there for an naif0012.tls, but the .tls is in the same directoy as spice2xyzv.exe ("D:/Celestia161/_Others/Apps/spice2xyzv/naif0012.tls". How can I fix the issue without moving the files to "C:/Program Files/..." and without hacking the .exe file?

[pedro_jg]

Whoops, I forgot I already had this file... Shouldn't be much of an issue to create that path and put just naif0012.tls there.
