A STUDY OF OPTIMAL LINEAR ESTIMATION FOR A HORIZON SCANNER,

Abstract

The theory of optimal linear filtering is applied to the problem of estimating the pitch attitude of an orbiting spacecraft. The horizon scanner model assumed includes the effects of instrument dynamics, instrument noise, and external noise, such as that due to 'cold clouds' and uncertainty in the definition of the horizon. The entire system, including the process model and the optimal filter is simulated on an analog computer, and the results are discussed and evaluated. (Author)
