This paper analyzes historical software development costs and schedules from military and NASA satellite systems. Cost-and time-estimating relationships were developed for ground segment and embedded flight software. In addition to the traditional size variable, other cost drivers were found: software residence (ground or flight), and software type (application and support). Schedule driving variables included size, staffing level, and residence. The equations developed from the study can be used to estimate future space system software development costs or to cross-check estimates generated by other methods.
