Research On Space Launch Software Development

With the development of information technology,space launch mission software plays an increasingly important role,has been distributed in various professional fields of various systems,especially small and medium size(usually 10 thousand lines of code below)software,the proportion reached90%.The software version is numerous,the frequent changes in the development process,and random emergencies,it is difficult to management in a software organization usually focuses on the little attention to the development process,software development is too dependent on personal heroism,software quality is difficult to control and inheritance.Military software capability maturity model GJB5000 A is led by the assembly of the Ministry of telecommunications,the CMMI of the software engineering(Software Capability Maturity Model Integration)on the basis of a set of military equipment software development process of continuous improvement,so as to ensure the quality of software requirements continue to improve,with the same strain of software engineering specification in 90 s the implementation of assembly command.2005 March assembly former minister Chen Bingde signed the quality management provisions of order No.4"Military Software,where the requirements of military software development has the functions of the unit" 12 th Five-Year "end must pass GJB5000 A level two or above,or they will cancel the qualification of the military software development.Based on this background,the XX center at the end of 2011 to carry out the GJB5000 A two level evaluation work,and in early 2015 by the assembly of the two level certification.In the three years since the development of certification system,carry out the system of writing,organization construction,training implementation,project to promote a lot of work,the software process management level has been greatly improved.And the cost is more controllable,software quality is improved significantly,two level system promotion since the software in the task does not appear due toineffective management problems.But in the process of implementation of promotion there are still many problems,such as software engineering and technical personnel lack of level,to co-ordinate the work of contradiction,the project management costs increase,the lack of organizational assets to a certain extent,affected the quality and effectiveness of standards.Therefore,in practice need to constantly sum up experience,continuous improvement process,protect the space launch escort.
