Dr. Quine maintains a keen interest in space instrumentation and have been involved with a number of space instruments including Argus, SOHO, XMM, CLUSTER, MOPITT, SCISAT-1 and PROBA. During previous research at the University of Oxford and in association with Astrium (UK) Ltd., he developed the basis for an algorithm to identify autonomously star patterns and to determine spacecraft attitude. In contrast to other approaches, the algorithm performs the complete identification process extremely quickly and efficiently and does not require a dedicated processor. The first space instrument (the Astrium AST20) to use the new approach was launched on the European Space Agency (ESA) technology demonstration spacecraft PROBA (PRoject for On-Board Autonomy) October 22, 2001. Other research interests include estimation theory, stochastic and Simplex retrieval techniques, planet detection, and the observation of extra-solar planetary atmospheres.
