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?
January time frame sounds good to me. There are a few items left with the ephemeris readers/writers that I would like to fix before the release. Also if Hank has time to contribute his OEM writer I think that would be good to include in 9.0.
I agree the flux data loading could use some improvement. Perhaps we could provide a loader for STK's flux files which would satisfy the Ap/Kp/F10.7 based models. ftp://ftp.agi.com/pub/DynamicEarthData/stkFluxReadme.txt
