Livingstone Model-Based Diagnosis of Earth Observing One

Abstract

The Earth Observing One satellite, launched in November 2000, is an active earth science observation platform. This paper reports on the development of an infusion experiment in which the Livingstone 2 Model-Based Diagnostic engine is deployed on Earth Observing One, to demonstrate the capability of monitoring the nominal operation of the spacecraft under command of an on-board planner, and to demonstrate on-board diagnosis of spacecraft failures. Design and development of the experiment, specification and validation of diagnostic scenarios and models, and the integration and test approach are presented.
