[Orekit Developers] Roadmap for releasing Orekit 9.0?



Hi all,

A lot of work has been done on Orekit since 8.0. Orbit determination
has been improved, we can now go from ephemeris file to propagation
directly, Taylor algebra has been added, some atmosphere models
have been added...

I just asked on the Hipparchus list if we could release Hipparchus
1.1, suggesting this could be done in late December. If this is
accepted, what about releasing Orekit 9.0 afterwards, probably
in January? Considering Taylor algebra branch which is already public
is expected to be merged soon in the master branch, the state of
the library is already worth a major release.

We may add a few things. Some co-workers here developed additional
features for orbit determination (maneuvers estimation and
turn-around measurements). There is also a very preliminary work
on Kalman filtering, but I don't expect this to be ready for 9.0.

I would be happy to also have some improvements on the solar activity
loading. Several people have expressed interest and even started some
redesign, but up to now we don't have a clear vision of where we want
to go. As this would probably introduce incompatibilities, we should
really think about it before the release.

What do you think?

best regards,
Luc
