Toutatis I appreciate your work on the Orbiter models you're converting and making for Celestia. Great job!
Thanks DaveBowman2001 :smile:

Update for TDRS satellites... TDRS 3, TDRS 5, TDRS 7, TDRS 10, TDRS 12.... SSC-file was changed... the correction which was made will direct the main antennas of these satellites right to the Earth...

DaveBowman2001... That's good... thanks.. :smile: :smile: :smile:

but for these orbital parameters you need to use OrbitFrame... because, this data was taken from HORIZONS and was used the Ecliptic as the main plane of the orbit... by default Celestia use the equatorial plane of the central body as the main plane...

Toutatis,

thank for all this models and .ssc :clap: :clap:

but for TDRS, there are 2 generations of satellites (see pictures)
TDRS 1 to 7: 1st generation with a hexagonal central body
TDRS 8 to 13: 2nd generation with a cubic body

In addition, the dishes and antennas are different.


In the model of 1st generation that I join you (source model of the site of JPL Nasa), it misses some parables and the internal surfaces of the parables are not vectorized to texture them, so that they remain transparent seen of the inside. Is it modifiable?

(the original file is a .lwo file)

About tess, fortunately, the lenses of the cameras are visible on your model... :biggrin:
There remains the problem of the antenna and the golden protections ...

FYI: gray protections are useful for transporting Tess to the rocket.

Before closing the cap, they remove all the gray protections (antenna, head, lenses). :wink:

Hello Gironde... Yes, I know about difference and I have all these files of models... and when the different a new model will be ready we will use it...

toutatis, I'm having trouble moving the antenna on the Compton GRO model that you gave me, as parts of the base of the antenna are indirectly connected to other parts of the spacecraft that I don't want to move, and I don't know how to avoid this...

No, it's a newer TESS, it's written on picture... :wink:

It would be better, right ?

Details seem good.

Hello

I was not completely satisfied with the Cassini-Huygens timeline, so I studied the dates provided on the web and the different models on Celestia Motherlode and those made by Toutatis.

I recombined everything with the .xyzv files of Toutatis and the scenario of the descent of Huygens on Titan where the different phases are very short.

Cassini-Huygens
Cassini only
Huygens orbit
Huygens descent phase 1 to 5
Huygens landed

I changed the names of the .cmod and .ssc files, so if you install it, remember to save your old addon, put it elsewhere so that it does not interfere.

For users of LUT5, I put a text file in which there are changes to be made to the guide where Cassini is, phase by phase. These modifications concern the path of the object and the time to see it.
