ATV avionic architecture

The functional architectrrre of the ATV aviotrics is a hierarchical modular organization of entities classified as  

For each functional rmit, a fmrctiotral rrrrit manager (FUM) provides the unit software services and is respotrsible for the cotrfigmation of the frmctional unit 

The avionics software thus includes software units and ftinctional unit managers. The mission and vehicle manager (MVM) has a particularly important role. It is itself divided into  

The organization of MM, VCM and FDIR in the MVM and their links to other software units and functional unit managers are detailed in section 7.7.4. 

The avionics of the ATV are located in a slightly conical section called the Avionics Bay , 1.36 m in height and up to 4.5 m in diameter, inserted between the cargo bay and the propulsion module.
