Clear EphemerisGenerators from Propagator

Orekit usage
1

Hi,

In Orekit 10 after calling Propagator.setEphemerisMode() I could call Propagator.setSlaveMode() to stop storing all the intermediate states. How do I do the same in Orekit 11.0? Propagator.clearStepHandlers() doesn’t seem to clear the generators list.

Regards,
Evan

It’s a bug! There is currently no way to remove a generator once added, but their should be a way to do it.
A dedicated clearEphemerisGenerators method should be added.

created #879 for it: Add method to clean ephemeris generators from Propagator (#879) · Issues · Orekit / Orekit · GitLab

Hi,
is there any news on this impletation ? I would reallt like to have the possibility to remove the ephemerisGenerator of a numerical propagator. Right now it seems that the only option is to create a new propagator but it is messy when I am working with a constellation of satellites.

Thanks in advance,
Davide

Hi @DDega,

Unfortunately, the issue is still opened and unadressed. For now i would say that the best way would be to use a PropagatorBuilder to build new equivalent NumericalPropagator without EphemerisGenerator.

Feel free to upvote the issue so that it can be prioritized over the others.

Cheers,
Vincent

Hi all,

I’ve started this MR.
Does it look like it’s solving the issue?
