Satellite Reliability Spectrum.

Abstract

Effort was made to develop a satellite reliability spectrum using as input data the known complexity of each operational function in the satellite and the observed operational orbit hours to malfunction, failure, or censoring. Each such observation will provide a point on the log-log scattergram of reliability versus complexity. From these points, a least squares regression line will be calculated, representing the middle of the satellite reliability spectrum. A distribution of observations at various complexities will be used to determine the width of the band about this line. A secondary purpose of the program is to develop more realistic component part failure rates for in-orbit applications. Results show that the predicted time to first malfunction or failure is considerably more pessimistic than the observed time.
