Would the community be interested in going beyond just cannon-ball model for SRP modeling? For instance, facet-based SRP modeling as in the reference: https://doi.org/10.2514/1.60577
I would like to develop and integrate the same if there is good enough interest in using the same.
Welcome to the forum !!
And thank you for your contribution proposal, that’s greatly appreciated!
However, know that there is already a facet-based SRP and drag model in Orekit
It’s called the BoxAndSolarArraySpacecraft.
For a long time, it could only model one set of drag and SRP properties for a given spacecraft. But @luc improved it a few months back (see this closed issue) and now each facet can have its own properties.
Now the model in Orekit is probably not perfect and I admit I haven’t read your reference yet so I don’t know if it will suit your needs.
What I invite you to do is to check the features in
BoxAndSolarArraySpacecraft class and, if you need some improvements, propose an enhancement of the class or a whole new class that would cover your requirements.
Hope this helps,
Edit: I’ve read the abstract of the paper you give as a reference and it is indeed much more complicated than what we already have.
Orekit does not have neither shadowing nor a bidirectional
reflectance distribution function model.
