As noted in the previous post, Orbit Toy and System Builder now come together, as Atomic Space Tools. This makes it a bit easier for me to make improvements to both at the same time, and makes swapping between designing and simulating a system a lot quicker.
Besides the integration there haven’t been any huge new features, but there are a lot of usability and in some cases accuracy changes. Perhaps most notable is that before ‘phase angle'(true anomaly) in System Builder was incorrectly saved and loaded. That is now fixed.
I’ve also thrown in a few more exoplanet systems and a close but not quite completely accurate rendition of the solar system from the game
Orbit Toy is a program that allows you to simulate and view the interactions of celestial bodies over time, through both graphical and command-line interfaces. It began as proof-of-concept work for the Atomic Space Navy project, and will continue to advance along with it.
Orbit Toy can be considered pre-alpha work. It is not feature complete, and the features present have much room for improvement. But at this stage I consider it both usable and potentially useful, so I’m making it available for download. More detailed instructions can be found in the included readme file.
