Software Complexity Measurement for Flight Software

The usage of software, which is used in variety of missions like Loe, Geo and interplanetary missions is increasing from mission to mission. The flight software size is increasing to take care of safety and security parameters, autonomy features and also to handle contingencies like failure detection, isolation and recovery. The growth rate of software will increase for future missions as new functionally gets added in software rather than hardware. This paper mainly concentrates on the software complexity metrics based on the static analysis carried out. This analysis helps to address the risks associated with development in size and complexity of flight software.
