FMEA-based designing and testing methods for satellite spaceborne guidance and navigation software

Abstract

The invention provides FMEA-based designing and testing methods for satellite spaceborne guidance and navigation software. The testing method comprises the following steps that S1, feedback of failure conditions is obtained from n second terminals; if failure type entries corresponding to the failure conditions are not recorded in a database of a first terminal, the S2 is conducted; S2, the obtained failure type entries are categorized into failure model types in the database, and corresponding failure type entries corresponding to all the failure conditions are obtained; S3, the S1 and the S2 are repeated, and the S4 is conducted in the repeating process; S4, according to the requirements of software to be tested, corresponding failure model types in the current database are indexed, and information designing and testing cases recorded in the failure type entries under the failure model types are referred to, so that running of satellite spaceborne guidance and navigation software on terminals is tested.
