Multi-Mission Operations System (MMOS)
Each mission needs to develop a Mission Operations System (MOS). Without a standard design to use as a reference, system engineers typically look to a subset of previous missions and develop a system with a mix of heritage, new design, and in some cases, reinvention of existing capabilities. If a reference...
