I’m happy to announce the first release of OpenC3 and the birth of our new company fully devoted to this technology!

After 16 years of developing Ball Aerospace COSMOS, its creators, Ryan Melton and Jason Thomas, have created a new company called OpenC3 so that we can fully serve this technology and its users.

This release continues where we left off with COSMOS 5.0.5 and is appropriately versioned OpenC3 5.0.6.

This release rebrands the product to OpenC3, has important bug fixes, improves overall performance, and has some great new features including the ability to create telemetry screens directly from the GUI without uploading a new plugin.

Key Enhancements

  • In TlmViewer you can now create screens directly from the user interface
  • Cursors are now more visible
  • All API methods now support different scopes
  • The command line interface now supports running as root for environments where that is needed
  • Better error messages for many errors
  • Conversions now serialize their output data types and sizes

Key Bug Fixes

  • Sending binary blobs in commands now works
  • The Script API now properly enforces authentication
  • Limits Monitor now handles plugins being deleted from under it
