Now it has an opensource optimization plugin (Yukon), and you don't need proprietary tools (VF13ad/Matlab) anymore.

Then I'm afraid it will be useless with my Windows 7

Yes, they really used GMAT for TESS mission, there is even "Generated by the General Mission Analysis Tool (GMAT)" text inside old ephemeris files ( https://spsweb.fltops.jpl.nasa.gov/p...emerides/TESS/ )

Thanks for the info, Ajaja. I think you are referring to this: gmat.sourceforge.net/doc/R2018a/html/Yukon.html

(I didn't know R2018a has been released. Probably missed it. Should check the news more often.)

MONTE is cool, I think. You should try learning Linux. It is fun. I dual-booted my PC with Windows 10 alongside CentOS.

IIRC, JPL uses Linux (RHEL) in planning mission trajectories. Not sure about Goddard. Since GMAT is available as a Windows application, I assume they run optimziations on Windows platforms.

Ya, I know that. Saw TESS's profile in several NASA documents. Will be more careful next time before posting. :p

JPL calls their mission planning software "Monte Python" ??!? :-D
Must have another look at GMAT, tried it years ago but got distracted by other things.
Thanks,
Brian
