C-DReAM is a Python implemented simulator with the capability to simulate various sized NGSO (LEO, MEO) and GSO satellite constellations. It’s a link budget / capacity level simulator that operates on a configurable time resolution.
C-DReAM is highly configurable, so it allows customer and project specific modifications.
