-I needed to calculate orbital characteristics for any orbit around any gravitational mass (because I write sci-fi stories), so I wrote this program because I'm a programmer and I'm too lazy to do it by hand all the time. The program has expanded over the last few years, sometimes from suggestions by other writers. I make it freely available and as simple to use as possible. It now has a list of functions as long as your arm (assuming you're not a tentacle user), and the number of downloads is now in triple digits.
+I needed to calculate orbital characteristics for any orbit around any gravitational mass (because I write sci-fi stories), so I wrote this program because I'm a programmer and I'm too lazy to do it by hand all the time. The program has expanded over the last few years, sometimes from suggestions by other writers. I make it freely available and as simple to use as possible. It now has a list of functions as long as your arm (assuming you're not a tentacle user), and the number of downloads is now in <del>triple</del> quadruple digits (1,223 at the time of this edit).
 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…”.
 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.
+It runs on **Windows** & **Linux** (32-bit and 64-bit versions available for both platforms), and there is an armv7l version too (can you say Raspberry Pi?).

 ===== Two Types of Orbital Calculation =====
 {{:blog:articles:software:twobody.png?direct&400 |Two-body calculation}}Users of the first versions of this program will be aware that the basic computation the program makes is for a satellite with an insignificant mass (vs the host gravitational mass). Simply select a mass and enter an orbital distance by typing in apogee and perigee (or just one for a circular orbit), then hit the calculate button. This is great for satellites and other types of spacecraft.
