Optimization of spacecraft architectures for earth-orbit satellite projects
Abstract/Contents
- Abstract
- Multiple-payload satellites in Earth orbit can be designed either as consolidated or distributed satellite systems. A consolidated satellite approach aggregates multiple payloads onto individual large satellites. A distributed (or 'disaggregated') satellite system allocates payloads across multiple smaller, heterogeneous satellites. U.S. space agencies have debated whether to move from consolidated to distributed systems for almost two decades. Two of the potential advantages of a distributed system include replacement of failed units more efficiently and insertion of new technologies more quickly and easily. Such a system may also be less vulnerable to adversarial threats. I create an approach to analyze the strategic choice between these satellite system-types. I model the value of a satellite program, and find optimal sequential decisions to choose and operate a particular satellite system. This model enables satellite architectures to be compared on the basis of certain equivalent, given a strategy that best-exploits the characteristics of each system alternative. This research finds that the choice between satellite architectures is highly sensitive to a decision maker's risk preference and the rate of technology advancement for payload instruments. This research is able to show that distributed satellite systems often provide greater value in programs that merit risk-averse decision making. Likewise, in scenarios where technology improves for payloads quickly year-over-year, distributed satellite systems often provide significantly more value than consolidated systems.
