The Data Storage application (DS) is a core Flight System (cFS) application that is a plug in to the Core Flight Executive (cFE) component of the cFS.
The DS application is used for storing software bus messages in files. These files are generally stored on a storage device such as a solid state recorder but they could be stored on any file system. Another cFS application such as CFDP (CF) must be used in order to transfer the files created by DS from their onboard storage location to where they will be viewed and processed.

The DS application is written in C and depends on the cFS Operating System Abstraction Layer (OSAL) and cFE components. There is additional DS application specific configuration information contained in the application user's guide.

cFS Framework (cFE, OSAL, PSP)

An integrated bundle including the cFE, OSAL, and PSP can be obtained at https://github.com/nasa/cfs

The cFS is a platform and project independent reusable software framework and set of reusable applications developed by NASA Goddard Space Flight Center. This framework is used as the basis for the flight software for satellite data systems and instruments, but can be used on other embedded systems.
