Abstract

This paper describes how fault tolerance has been addressed in the design of the Attitude and Articulation Control Subsystem for the Saturn-bound Cassini spacecraft. Cassini´s fault tolerance objectives have strongly influenced the subsystem´s level of autonomy, and have motivated some significant improvements over the autonomous capabilities of previous interplanetary spacecraft. Autonomous fault tolerant behaviors have been embedded at several points in the object-oriented flight control software, including a dedicated set of failure detection, isolation, and recovery algorithms
