C-DReAM is a Python implemented simulator with the capability to simulate various sized NGSO and GSO satellite constellations. It’s a link budget / capacity level simulator that operates on a configurable time resolution.
With C-DReAM, you can evaluate satellite system capacity, optimize constellation parameters, analyze the coexistence of satellite and terrestrial systems – and more.
C-DReAM is highly configurable, so it allows customer and project specific modifications.
