Thanks very much Gironde... I will learn... ... but about TDRS... I used Wings 3D to join the main antennas... and now it looks better...

Hello Gironde... thanks for these great add-ons... plz, can you describe all process of convertation from FBX to CMOD... in case with TERRA or other FBX models... I have problems... all models I convert from FBX are without color and texture... I also use Blender, Autodesc FBX Converter, MeshLab and...

toutatis, hey. If I see again that you are demanding money for any your add-ons, I will block your account.

Alexell... Did you seen it again??? I earn well with my main job... so no worries...

Thanks very much Gironde...
but I made this TDRS...

Gironde... in COSMOS 2237 SSC file... TLE DATA from NORAD gives the orbital elements for the Earth Mean Equator... not for Ecliptic... so there in SSC file no need to write Orbit frame... Celestia will use the Earth Mean Equator by default...

Use this...

Hey Gironde... Thanks a lot for COSMOS 2237 !

Try Wings 3D... I use it often

Does anyone having practice in 3D software can put everything in order: add textures, add antennas, ...

I learning this work... hope with time I will be an professional... lol

Hi guys... Okay I can see that work with spacecrafts is continues... great!... Thanks... I got lot of work these days but I made this... TDRS 3.. 5.. 7.. 10... 12.. TDRS satellites with a big antennas, so I use this model ( modified it a bit ) 5 geostationary satellites... need only change Orientati...

hello Toutatis, thank you for explications but Suddenly, my head hurts ! :biggrin: :biggrin: :biggrin: :think: Hi Gironde... Yes, I can understand it... :biggrin: :biggrin: :biggrin: I retrieved the 3D file for TDRS 11, geostationary communication satellite from NASA TDRS 12 and TDRS 13 are from th...

Hi Toutatis. I just tested your TESS model, very nice, but it has a bit cahotic rotation. So I checked the ssc file, and I found that Orientation is "[ 250 1 0 0 ]" instead of "270 1 0 0" that produces a rotation around TESS longitudinal axis. What is the correct axis angle, 250...

Hey guys... XYXV-file for OSIRIS-REx journey is ready... let's prepare model of this spacecraft for an add-on... I will do SSC file too... ( The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is a NASA asteroid study and sample-return mission. Lau...

Thank you, Toutatis, very appreciated.
Bye

I looked at these 3 sites and I find that they give conflicting definitions even in their own lines. They talk about the 2 focus points but we never know them. If you know the definition of semimajoraxis that goes well with Celestia, I'm interested. Hi Gironde... problem only that I do not know Eng...

Add-on TESS... SSC file from "Celestia Origin", I just changed it abit... + TESS (cmod model)...

Hi Toutatis.
Can you please upload TESS ssc file?
And, just curious, why this one is 3DS only while your previous one was cmod too?
Thanks a lot.
Goofy

Okay Goofy... I will upload SSC file... and convert 3ds file to cmod file... just wait some mins plz...

Today I want to start working with the main antenna for TESS... becoz at the 2 models that we have it looks not well in Celestia...

TOPEX/Poseidon was a joint satellite mission between NASA, the U.S. space agency; and CNES, the French space agency, to map ocean surface topography. Launched on August 10, 1992, it was the first major oceanographic research satellite. TOPEX/Poseidon helped revolutionize oceanography by providing da...

The Aeronomy of Ice in the Mesosphere (AIM) is a satellite to conduct a 26-month study of noctilucent clouds (NLCs). It is the ninetieth Explorer program mission and is part of the NASA-funded Small Explorer program (SMEX). On April 25, 2007 AIM was boosted into a 600 km (370 mi) high polar orbit by...

I was attentive to what you emphasize but that's what I find on wikipedia: Half-major axis a : half of the distance between the pericenter and the apocenter (the largest diameter of the ellipse). This parameter defines the absolute size of the orbit. It only makes sense in the case of an elliptical...
