Our DSM explores the uses and applications of different technologies within the autonomous space exploration taxonomy. We classified interplanetary small satellites within the orbiting spacecraft section of interplanetary autonomous spacecraft. The subsystems are listed within 4SMS, but could apply to most of the other technologies that stem from 2EOT or 2IPT.

In the top box, the higher level systems are categorized with regard to their applications. These are defense, science, and servicing. Defense refers to spacecraft that can be equipped for surveillance, intelligence, or weaponry. Science refers to spacecraft whose primary purpose is to collect and relay scientific information. Servicing includes spacecraft that support other preexisting missions or Earth-based systems such as Internet or GPS. We further explored what subsystems that are common to most spacecraft might support either of those three applications. Some boxes represent impossible connections; a spacecraft is either Earth-orbiting or interplanetary, it cannot be both. These intersections are highlighted in light gray.

The bottom box classifies the purpose and relationships of the subsystems that may make up an autonomous spacecraft. The three categories are information processing, transportation/navigation, and system support. If two subsystems do not have meaningful interaction, the box is left blank.
