Abstract: With the rapid development of the space technology,the highreliability of Space products is required.It is very important and complicatedto calculate the reliability of space products.Once the design is determinedthe reliability will be first calculated.Therefore,the calculation of reliabi-lity is defined to be a key link not to be neglected in the development of sa-tellite.This paper provides an approach to calculate reliability of electronicproducts in the satellite,such as meteorologic satellite FY-1.

Key words: Subject Term Meteorological satellite, Reliability prediction, Electronic device.
