Abstract
Unmanned Aircraft System(UAS) is a huge and complicated system that is composed of UAV, ground control system, datalink system, and mission equipments. We have applied system engineering to development of UAS. Configuration management is very important activity for efficient developments. The Configuration management process comprises four distinct disciplines (Configuration identification, Configuration control, Configuration status accounting, and Configuration audit). This paper explains the configuration management system of UAS development project which ADD executes and introduces several examples of these four disciplines.
