Digital Solid State Propulsion (DSSP) is an aerospace company developing microthruster propulsion technology for small satellites. DSSP's technology utilizes Electric Solid Propellants (ESPs) to enable small satellites to make orbital maneuvers that have generally not been possible in the very small, mass-constrained satellites such as CubeSats and nanosats. In July 2012, DSSP won second place in the 2012 NewSpace Business Plan Competition in Silicon Valley, sponsored by the Space Frontier Foundation.
