Super awesome! Since this package seems not to be available as OpenSource, I'm trying to get some ideas here since I'm working on a similar topic, not related to space craft dynamics, but to inertial sensors which share a lot of the mechanical parts. How many man hours did you spend approximately? Do you have time discrete states or is this a fully continuous simulation? You mentioned to use MTK in future if you had to do the same thing again, is that still true? :) Thanks!
@jonathan! Thanks for presenting. I am trying to implement this in simulink. However, julia project seems even better. Do you have an unclassified gitlab repo that you could share for this work ? Thanks
When I started this project, ModelingToolkit's component system wasn't quite mature enough yet for me to feel comfortable writing the whole sim in it. These days, however, it's really nice. I use it all the time now. If I were to start this over from scratch, that would be my choice. Actually, I'm considering migrating the sim to ModelingToolkit anyway because it's much easier to inspect intermediate variables like spring forces when you can make them symbolic aliases.

@UCw6StaYMjPHPKRqOMGUaVaw Oh cool, I met Neil about a year ago when we were working with the NESC on a different project. That sounds great, have him shoot me an email. Thanks!
I'm glad to see that NASA is using Julia more. Great work!

Fascinating talk! thank you!
Very interesting case study.
Please, what do you use for interactive plotting at 14:01 ? Thank you
Just a Pluto notebook with sliders from PlutoUI.jl.
@jonathan: where can I find more info on how to develop this for myself? Books, articles, etc

Unfortunately I don't have anything I can make public yet. I am working on getting it approved for open source release, though.
Nice work .. we did it in SimScape.. though Julia is more natural.. by the way Modia and the ModellingToolkint will give you
even more power...

Your colleague at NASA may contact you if you want to present this work at the upcoming InterAgency V&V workshop

@@jonathandiegelman4714 great just sent him a WhatsApp..,
Where can I learn more about spacecraft dynamics?
Is it possible to get the source code?
