What do you mean by "work(ing) with a robot arm around the module"? And the grapple fixture will only be for installing the module.

For example, you want to assist astronauts during an EVA near this module. Or you want to dock a module or spacecraft (think SpaceX Dragon) at the unused CBM of your module.

REMEMBER: you designed your module with a CBM at the ends. CBMs are no docking ports, but berthing ports, they have for example no means to absorb the impact of a spacecraft during slow docking (The shuttle for example has the same impulse during docking at 5 cm/s as a typical car at 5 m/s or 17 km/h). The CBMs require a robot arm to bring the two CBMs together and hold the opposite spacecraft/module until the connections are established.

I knew that.

How long is your module? The minimum distance between CBM and spacecraft before grappling is 10 meters. The SSRMS can reach 17.6 meters when fully extended. This is the furthest distance with all limitations in degrees of freedom, except one: reducing the distance, to have more freedom.

You need a PDGF if you want to use it as a base for the SSRMS.

 

[Urwumpe]

About 13.19 meters.

So, unless you add a PDGF somewhere at the end, you can't berth something to your CBM - it would be much more than 23.19 meters to the spacecraft from the PDGF that you used for installing your module to the spacecraft/module

Can there be one near the antenna?

yes, but better put it at an angle there (not on the same "longitude" as the antenna), so you can reach the other CBMs easier.

On the end that points to the center of the station, you can leave a FRGF, since you will likely have a PDGF on the other module there... or do you plan to use your module as first module of the station? Then four PDGFs make sense.

By the way, I've never seen a module add-on that had PDGFs like this. I mean, no one told someone to add those connector sockets before.

Do you want quality or do you want just another module? :lol:

Just remember, improvements aren't always necessary.

(telling that to any people who want to develop station module add-ons)

Actually, I don't think that would be possible because the attachment point system in the config doesn't allow for that kind of angle. So I'll put it on the same "longitude"

Have fun snapping the aerial off with the arm then.

Looking good to me so far. I like your attention to detail. Keep up the good work!

Wrong. you have all 6 degrees of freedom.
