A Cost Analyst's Guide to Satellite Autonomy and Fault-Tolerant Computing,

Abstract

The trend in satellite design is toward greater autonomy in satellite functions, particularly in attitude determination and navigation. Fault-tolerant computing is a necessary condition for autonomy, and incurs costs in terms of computer memory, throughput, power and weight. Fault-tolerance and reliability issues need to be looked at and estimated early in the system development. This could prevent cost overruns due to lengthened test programs and unexpected redesigns. Finally, space logistics is becoming an area of increasing interest and study. The costs of space transportation and modular designs for on-orbit replacement of components need to be weighed against the cost of building increasingly intelligent and autonomous satellites.
