抄録(英) | The author statistically analyzed on-orbit failure data of recent Japanese satellites based on primary investigations of satellite failures. Random parts failures are only 11% among failures whose causes are identified after investigations. Instead failures caused by design defects (57%) and manufacturing defects (32%) are dominant for on-orbit satellite failures. Propulsion and solar paddle subsystems have a relatively large number of failures caused by design and manufacturing defects, against which redundant system are uncertainly effective. Mission instruments have a large number of failures caused by design defects. Bus subsystems except for propulsion and solar paddle subsystems have a relatively small number of failures. For these bus subsystems, failures tend to happen deterministically and redundant system may not be effective. |
