The Wideband Global SATCOM (WGS) is a high capacity USSF military communications satellite system operated jointly by the United States, Canada, and Australia. Currently there are 10 satellites launched into GEO since 2007. An 11th satellite will be launched in 2024 from either a Vulcan Centaur, or a Falcon 9. After the sixth satellite was launched in 2013, it effectively replaced the old Defense Satellite Communications System (DSCS) program, which has been operational since the 1960s. The satellites were manufactured by Boeing using the HS-702HP mainframe

Orbit parameters based on TLE data. All satellites are operational as of 2021-Sept-2

NASA's Lunar Orbiter program was a series of five uncrewed lunar orbiter missions launched by the United States from 1966 through 1967. Intended to help select Apollo landing sites by mapping the Moon's surface, they provided the first photographs from lunar orbit and photographed both the Moon and Earth.

Orbit parameters are based on available data from NSSDC (thanks pedro_jg!). All spacecraft are no longer orbiting the Moon since 1968

PROBA-1 to 3
series of low-cost European Space Agency (ESA) micro-satellites for the development of new space technologies.

PROBA-1 : 2001-049B launch date : 22 October 2001 04:53:00 UTC
PROBA-2 : 2009-059B launch date : 2 November 2009 01:50:00 UTC
PROBA-V (Vegetation): 2013-021A launch date : 7 May 2013 02:06:31 UTC
PROBA-3 : project 2023

3D models PROBA-2 and PROBA-3: http://scifleet.esa.int/#/model-downloads
PROBA-3 is composed of 2 satellites PROBA-3 CSC and PROBA-3 OSC.
They are designed to sail together separated by approximately 144m.
The model is supplied with the 2 satellites together or separated.


There are no 3D models for PROBA-1 and PROBA-V, so I used the model from PROBA-2

Orbital data is from https://celestrak.com/satcat/search.php for 1-2-V and
from https://earth.esa.int/web/eoportal/satellite-missions/p/proba-3 for Proba-3

This achievement certainly remains to be improved.

(if you are not using Vidiba from LUT5, you can override the 'Visible false' parameter)

Fault
for the 5 Lunar Orbiter probes, the Period is less than zero

Despite the modification, the display of the five probes causes a fatal error in celestia

the use of a generic model does not pose this problem

[SpaceExplorer]

hello Gironde

I've been using Celestia for a while now, I'm new to the forum and I found spaceship addons here and am adding them to my Celestia. I don't use Celestia Origin, I use Celestia normal. As for the PROBA satellites addon, is it necessary to open the ssc file to make the PROBA satellites visible? My computer doesn't open ssc, lua, I don't even understand that much. If possible could you send a version of PROBA in which to see the models in Celestia no action is required? But only if possible. Thanks.

[selden]

@SpaceExplorer,

I'm not Gironde but here's a .celx script to make the PROBA satellites visible.

Instructions:
Extract the script make_proba_visible.celx anywhere convenient
Then, while running Celestia, select (double-left-mouse-button-click on) the script's icon.
It'll make the satellites visible.
It does not take your viewpoint to any of them, though. You'll have to do that yourself.

[SpaceExplorer]

It worked, when I activate the script all PROBA satellites become visible. Thanks for your support, Selden!

Hello, SpaceExplorer!

You can open any XYZ, XYZV, SSC, STC, DSC, and LUA file using WordPad and/or NotePad

Fault
for the 5 Lunar Orbiter probes, the Period is less than zero

Gironde, the orbital period of the Lunar Orbiter probes are intentionally less than zero to simulate a retrograde orbit around the Moon, which the probes and every other spacecraft (including Apollo and LRO) do in real life.

Despite the modification, the display of the five probes causes a fatal error in celestia...the use of a generic model does not pose this problem

Strange...I haven't replicated this issue on my installation (both Origin and standard). Can you describe when in the simulation Celestia crashes as you visit any of the Lunar Orbiters? Thanks

[SpaceExplorer]

Hi DaveBrowman2001, thanks for the suggestions to open such files!

[DaveBowman2001]

The James Webb Space Telescope (JWST) is a joint NASA–ESA–CSA space telescope that is planned to succeed the Hubble Space Telescope as NASA's flagship astrophysics mission.

This addon contains only the XYZV trajectory made from the latest update from HORIZONS to reflect the upcoming launch of the telescope from French Guiana this December 18th. Download first the model and textures made by toutatis here

I select Lunar Orbiter 1 for example then I go there by the keyboard command 'g'. Arrived in the satellite area, Celestia begins to approach and at a time when we will begin to distinguish the satellite, Celestia closes.
I changed the mesh to the generic that I usually use 'satgeneric.cmod' and there everything works fine. That's why I think the problem comes from the 3D model (12300Ko) which seems a little too heavy to support by Celestia or the PC memory (8Go) or by the number of vectors.

Ok, the error that I thought came from the negative number, comes in reality from the 3D model.

To view the Proba satellites, you can use the script provided by Selden, which allows you to view them on demand. This is what the Vidiba module of LUT5 does
If you want to see them constantly without doing anything special, you have to edit the ssc files by a text editor (Wordpad, Notepad, Notepad ++, ...) in which you just have to delete the line:
Visible false
and save your modification.

Lua is a scripted programming language that is integrated with celestia. This is the language used by celx files and by LUT5
dsc, ssc, stc, xyz, xyzv, cel, celx are text files used directly by celestia to define objects
dsc: deep sky objects
stc: stars
ssc: everything that revolves around stars, plnets, moons, asteroids, spacecraft, ...
xyz, xyzv: files for chronological positioning of an object
cel, celx: programming script performing a particular action

This is the advantage of Celestia that it is quite easy to modify or supplement the basic delivery.

I've been on Celestia for many years and I'm still learning

[SpaceExplorer]

I managed to open the ssc files from WordPad, removed the visible false and now all satellites are showing up in Celestia. I'm downloading more gironde and DaveBowman2001 addons that have false visible to modify them.

Thanks for everyone's tips!

But could any of you send me a version from the 1st launch to the latest Starlink satellite launch? Or maybe a script? Because if I erase the visible false from each Starlink satellite, I'll be doing that for the rest of my life...

[gironde]

SpaceExplorer use notepad.exe and his fonction 'replace'

you must replace 'Visible' by '#Visible' (replace all)

I see. Apparently, the problem is coming from the CMOD model itself.

I also see this similar situation whenever I visit the high-definition ISS addon by linuxman where Celestia itself crashes (source of the problem is apparently coming from the Canadarm models). Initially I thought this is only an isolated case on my computer.

Unfortunately I currently do not know how to fix this aside from removing the model entirely from the simulation. But, I might revisit the Lunar Orbiter addon in the future after I'm done with my future projects (currently making a "Mark Asteroid Belt" script using the CO asteroid database in addition to filling some missing entries)

[SpaceExplorer]

DaveBowman2001, good you remembered the linuxman ISS model. It's a very detailed model, I've already tried it on Celestia, but Celestia crashed absurdly and even failed. Here: https://nasa3d.arc.nasa.gov/models . we have some other models for ISS, maybe these models are lighter and in the future can be used for a new ISS addon. Also, in linuxman addon, renders many missions to ISS, maybe this helps to crash too. For weak computers, I think it should just be the ISS model itself, without showing any missions.

[DaveBowman2001]

Linuxman's ISS addon is directly derived from the site you provided, SpaceExplorer. But yes, since it's so highly detailed it couldn't render properly in weaker graphics. In spite of this, it is still one of the most beautiful spacecraft add-ons ever created
