- | Orbital Calculator is the result of satisfying a need. There are online calculators for working out the orbital characteristics for satellites and spacecraft orbiting Earth, and they’re pretty cool gadgets as far as that goes, but quite limiting. | + | I needed to calculate |

I wrote Orbital Calculator to handle just about any proposition. You can add new gravitational masses (the things you want to orbit) for easy and consistent recall. You can add satellites too, so you can recall their orbital data at any time. You can create temporary calculations (not stored for later recall), and you can edit orbital parameters without changing the stored data, so you can play “what if…”. | I wrote Orbital Calculator to handle just about any proposition.

Even better yet, you can export any data for satellites or gravitational masses – choosing exactly which ones to export – and share the files with other users, who can import them into their own databases. | Even better yet, you can export any data for satellites or gravitational masses – choosing exactly which ones to export – and share the files with other users, who can import them into their own databases. | ||
