| Abstract: | Reliability of fibre-optic gyroscopes(FOGs) used for satellite exposed to space radiation was studied based on degradation data.With the great technology progress on FOGs in recent years,more and more FOGs have been applied in all kinds of satellites for attitude control.For satellites always have long lives,reliability of FOGs used for satellites has been focused on.Based on analysis of degradation mechanisms of FOGs under radiation environment,Normal-Poisson hybrid stochastic process model was presented a... |
