FreeCAD in space!

Postby papamat » Tue Jun 13, 2017 4:39 pm

Hello again, I am Manthos From the Libre Space Foundation (creators of SatNOGS). I have postpone this post a lot of times for many reasons but I think that the time has come. Last year, LSF designed, programmed and built UPSat the first completely open software and open hardware satellite. The project started from the university of Patras but the university failed to deliver it on time. LSF came to the rescue and design built almost all parts of the satellite in a 7 month period. The biggest part of the mechanical part was already made by the university in a proprietary software. A part that was missing was the communication antenna system and the placement of the GPS antenna. So, an antenna deployment mechanism was needed to be made. After a lot of prototypes and back and forth between FreeCAD and KiCAD the final part was ready.
All the parts and changes tracked in github.

Final design in FreeCAD

Some first prototypes

Fixed in a prototype chasis for RF testing

The final design (you can see how the lid is kept closed by a string attached on e resistor. In order to open you just pass some current from the resistor, it heats up and burns the string)

This is a video from the last release sequence we run before deliver the sat.

This one is taken the day we deliver the sat and this is the fit check procedure

And this one... (UPSat is the left most in the picture and you can see the antenna release system before release)

This I the first beacon we received from UPSat in space! (Means that everything went superb!!!)

Cool! FreeCAD in space race :D

I'll contact you via PP, maybe I have something interesting for Libre Space Foundation.

Great! Cool collaboration between FreeCAD and KiCad!!!
Nice to see this couple in real action! ;)
