Orbital Calculator

Current Version

This is a portable application, meaning there is no installer. Just unzip into a folder and run the executable. Since it is portable, it can be run from a USB stick.

A full description and a list of the features are available here.
Release notes are available here.

If you run the program in Gnome, there is a bug in Nautilus that prevents the program from running. You'll either have to run it from a terminal window or through a desktop icon. You can download this sample desktop file, which will need editing:

  • edit the Exec path to point to the application
  • edit the Path path to point to the same folder (this sets the working directory)
  • save the changes, then rename the file to orbitcalc.desktop
  • copy or move the file to /usr/share/applications
  • copy or move the image file earth128.png to /usr/share/icons

You should now be able to see the icon when you select the applications grid from the taskbar, and from there either launch it or add it to your favourites. Depending on your setup, you may have to log out and back in again to force the applications grid to refresh.

Older Versions

Format Windows (XP to w10)
32-bit Only runs in 32-bit mode

The v1.x series are much smaller and lighter on system resources, so may be a good choice if that's what you need. Note however, there are some known bugs in it (although they're subtle enough you probably won't notice them), and the functionality is limited.

Upgrading Orbital Calculator

Upgrading from v1 to v2

Unzip the new version into a new folder and run the program. In the Application menu, select Import Data and select your v1 database (orbit.dat).

Upgrading from v2 to a later version of v2

Simply unzip the latest version over the top of your current installation. Your data files and preferences will be retained.
