Abstract
Reliability analysis using satellite failure data for satellites launched in the years 1991-2020 is presented. The analysis is conducted using nonparametric as well as parametric methods. In order to derive a nonparametric reliability estimate from the raw failure data, the Kaplan-Meier estimator is utilized. The Weibull distribution is then utilized to attempt and parameterize the behaviors seen in the nonparametric results. To better interpret the data, data is split into groups with respect to launch dates. Results from this analysis show a general increase in overall satellite reliability over the previous 30 years.
