User Reviews

  • Great product. Runs fine on Windows 10, but is poor on Windows 11. For example, many of the drop down menus are not large enough to show all of the selectable parameters (see the parameter list in the ReportFile menu).
  • This is an awesome Trajectory Design tool!!! Thanks NASA Team.
  • I am absolutely delighted with this product and I want to thank the outstanding NASA and subcontractor developer team. Sometimes people forget this kind quality comes at zero cost to users worldwide. If that is a fault (and it is not), I admit to being an educator now although with a NASA/JPL past. My students love NASA GMAT. My teaching benefits immensely from GMAT and OpenFrames speaks well to this generation of students. The notion to have GMAT developers even respond to criticism is incredible considering that extremely expensive products are far less consistently backed up these days, not to speak of other FOSS tools for orbital mechanics without any real support over the years. Of course, as an old Fortran cat, I hope that Copernicus as well can be released to the public. But for now, thanks for NASA GMAT!
  • i use this program for work sometimes, and have been using it since 2017. stability is poor and usability is worse and not getting any better. the visualization capabilities are mostly useless to me as a trajectory analyst. you can visualize constellations and their names (nerds), you can supposedly connect a VR headset (nerds), but you cannot visualize the thrust vector, which is something that would be actually useful. the xy plotting capability is prohibitively slow. i typically will run GMAT headless and then use an external tool for plotting and 3d visualization, but that is far from an ideal situation. i'm sure the people that make GMAT are nice but damb.

    Hi Peter! I'm Ravi, the creator of GMAT's new OpenFramesInterface (OFI) visualization plugin, and I'm sorry you have had such a negative experience. Your thrust vector idea is a great one that has been requested before so I'll get on it. BTW, Copernicus is another trajectory design tool that you must be familiar with at JSC. It uses the same underlying viz library as GMAT's OFI and does show thrust vectors, so that won't be hard to add to the OFI. Feel free to submit bug or feature requests at https://gmat.atlassian.net/jira/software/c/projects/GMT/issues/ . The GMAT team would love to hear ideas from a trajectory analyst like yourself, especially since we all work on related projects/missions and all run in the same proudly-nerdy circles!
  • So happy that you guys decided to support Mac and making it super easy to work with. Keep up the good work!
