Where can I get up to date orbital elements for the Cassini spacecraft in
.edb or TLE format? I have tried getting some data (i.e. stations.txt,
science.txt and tle.txt from celestrak.com) with the XEphem "Data/Download
Internet files..." dialog, but they do not include a Cassini entry.

Nobody seems to publish orbital elements for the Cassini spacecraft in
.edb or TLE format, however this will work for a while:

Cassini,e,0.824258,126.814738,168.136273,5.373454,0.079127,0.728579,69.962587,12/01/2001,2000.0,10.0,1

NOTE: The magnitude information is bogus. Ignore it.

For more information on where Cassini is see:


And if you really want orbital elements for Cassini, see

then learn how to use the telnet or email versions.

I used the telnet facility to get the information, then wrote a quick
perl script to convert it to the edb formatted line above.

Cheers,
Dean

Is this because of technical problems, or maybe the current position page
at the Cassini site is considered adequate?

Yes, I've found these useful resources shortly after posting my message.


Thanks for the info,
