Abstract:

High reliability satellite requires the extremely high reliable assemblies over a long period of time. Within severe time constraints, this paper utilizes the accelerated degradation testing to evaluate their reliability and life. Firstly, the critical functional modular and its degraded failure mechanism of microwave radiometer Imager (MWRI) are analyzed to determine,the its accelerated model.
