Mass rate and additional derivatives

Orekit usage

Hello everyone,

When using (Field)AdditionalStateDerivatives, it is possible to update the rates of the orbital vector via the combinedDerivatives method. Is there no possibility to modify the time derivative for the mass?

Cheers,
Romain.

The ugly workaround I found is to add yet another additional derivatives provider to keep track of the consumed mass without using the one contained in SpacecraftState. I think it should be added in the future a way to directly modify the mass rate.

Cheers,
Romain.

Nevermind it seems actually possible to modify the mass rate via the seventh element of the main derivatives in the combined set. Dunno why it didn’t work the first time I tried. Hopefully this can help other users.
