“…Current trajectories of CubeSat development suggest that the time will come when the majority of computationally intense tasks onboard a CubeSat will be those associated with autonomous decision making and science data handling [73]- [75]. However, at present, GNC tasks still consume a nontrivial portion of cyber resources.…”

We propose the application of state-space techniques to develop a novel coupled cyber-physical system (CPS) model and use feedback control to dynamically adjust CPS resource use and performance. We investigate the use of a gain scheduled discrete linear quadratic regulator controller and a forward-propagation Riccati-based controller to handle the discrete-time-varying system. We demonstrate the value of our approach by conducting a disturbance-rejection case study for a small satellite (CubeSat) application in which resources required for attitude control are adjusted in real-time to maximize availability for other computational tasks. We evaluate CPS performance through a set of metrics quantifying physical system error and control effort as well as cyber resource utilization and compare these with traditional fixedrate optimal control strategies. Results indicate that our proposed coupled CPS model and controller can provide physical system performance similar to fixed-rate optimal control strategies but with less control effort and much less computational utilization.

“…The M-Cubed/COVE 1U CubeSat. This project will validate technologies for the ACE decadal survey mission [8], but similar efforts are also laying the groundwork for future lowcost and rapidly deployable sensor web technologies. Industry and academia are planning future missions using multiple CubeSats for collaborative observations.…”

“…Advancements in compact instrument technologies, communications, and availability of launches make these an ideal platform as a spaceborne sensor web for scientific observations and technology validation. While ESTO is currently investing in CubeSat technology validation projects for the ACE [8] and HyspIRI decadal survey missions, in the future one can foresee how these platforms can serve as precursors to help establish and refine observation requirements for future missions. Indeed they can also be the basis for small satellite based Earth observation sensor webs/constellations themselves to complement the decadal survey measurements.…”

This paper examines the Earth science decadal survey era and the role ESTO developed sensor web technologies can contribute to the scientific observations. This includes hardware and software technology advances for in-situ and in-space measurements. Also discussed are emerging areas of importance such as the potential of small satellites for sensor web based observations as well as advances in data fusion critical to the science and societal benefits of future missions, and the challenges ahead.
