Hybrid Space Architecture A New Space ecosystem opens the door to the consideration for a multi-layer system architecture that would aggregate multiple information sources, whether they be from traditional space, SmallSat systems, commercial services, or foreign partners to collectively enhance the information pipeline to the end user, while supporting increased on-orbit capability and overall resiliency. This multi-layer system architecture is called HSA.

This framework makes decisions and takes actions based on the trust of the derived data sources -- ensuring the security and integrity of all data and services. TECHNOLOGIES KEY TO A SUCCESSFUL HSA With the growth and diversity of the space community, significant capability is coming on line through allied and commercial sources.

A system can be considered operational when sufficient testing has been completed to demonstrate an appropriate level of reliability. To satisfy a capability requirement, users of future space architectures will need to be able to take advan TABLE 3.1 HSA User Hierarchy DoD Users of Space Assets Reliability Risk Avoidance Cost Pace of Change Level of Trust Operational Users High High High Low High Test and Integration Medium Medium Medium Medium Medium Users S&T/R&D Users Low Low Low High Low NOTES: Three primary DoD user categories are shown that all reap benefits of an HSA.

They range from tactical operators to the S&T/R&D community and may have specific data requirements, sensor designs, or even prototypes they would like to launch on short timelines. For those users traditionally underserved by current space assets, the HSA will be a major step forward.

EVOLVING HSA FOR A BROAD SPECTRUM OF USERS Technical Challenges HSA could be the basis of a national space ecosystem servicing not only top-level military users, but a broad spectrum of other users, including those in DoD, civilian agencies, universities, and private industry. The primary challenges of HSA are the complexity inherent in this type of architecture, because it requires a variable trust framework and the ability to perform data fusion and network automation.

While the commercial space industry is enjoying considerable private investment today, it will need reliable customers for the long term. The government will need to be one of the key customers of the capabilities offered by the envisioned space ecosystem.

RECOMMENDATION: The Office of Naval Research (ONR) should consider the Hybrid Space Architecture framework as an opportunity to fulfill its long-term ocean science objectives.
