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.

Description

technical field [0001] The invention relates to the field of spaceborne guidance and navigation, in particular to a method for designing and testing satellite spaceborne guidance and navigation software based on failure mode analysis. Background technique [0002] Spaceborne guidance and navigation software is an important control software for satellite spaceborne computers. It has complex control models and algorithms: guidance and navigation control needs a large amount of content, new control functions are diverse, algorithm applications are diverse, and various control process constraints The characteristics of complex factors. [0003] The existing technology generally adopts the traditional method of software product assurance to ensure the quality of the software. The reliability and security testing and verification methods still remain at manual code review, testing based on personal ability and experience, reliability and security requirements analysis results and ...
