The purpose of a command and data handling subsystem of a spacecraft is to ensure that an autonomous control of spacecraft functions is maintained. This must be achieved in order to receive, validate, decode, and distribute commands to other spacecraft subsystems and gather, process, and format spacecraft housekeeping and mission data from all spacecraft subsystems for downlink and use by on-board computer (OBC). Therefore, command and data handling subsystem becomes the brain of the satellite and its reliability, efficiency, autonomy, redundancy and sizing affect all subsystems of spacecraft. This paper describes the details of the command and data handling subsystem of GÖKTÜRK-2 Flight Model. Technical descriptions of each component with their interfaces are presented including their data links. The operational workflow of the subsystem is also presented to show how BiLGE OBC accomplishes this important task by using its software task architecture.
