A Quality Measurement Method For Maintenance of Space TT&C Software Based on Objective Data

Space TT&C software is the brain and central nervous system of the integrated space TT&C system of earth and sky. Its quality directly determines the success or failure of space launch TT&C mission. For each mission of the space TT&C software, application maintenance development needs to be performed on the software system accumulated over the years. The application maintenance process is closely integrated with the mission organization implementation process. According to the attributes of each stage of the application maintenance development process, the quality parameters are calculated based on the actual accumulated objective data, and then the stage quality assessment factors are determined. The proportion of each quality assessment factor is determined according to the degree of influence on the result. As the dual factors of efficiency and quality comprehensively considered, a quantitative measurement method for the maintenance quality of the space TT&C software based on objective data was established. The method can be used to evaluate the preparation status of the applied software before the implementation of the space TT&C mission.
