The Health and Safety application (HS) is a core Flight System (cFS) application that is a plug in to the Core Flight Executive (cFE) component of the cFS.

The HS application provides functionality for Application Monitoring, Event Monitoring, Hardware Watchdog Servicing, Execution Counter Reporting (optional), and CPU Aliveness Indication (via UART).

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

User's guide information can be generated using Doxygen (from top mission directory):

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. More information on the cFS can be found at http://cfs.gsfc.nasa.gov
