5.1. Subsystems#
The previous section introduces the concept of Device Control Subsystems. The Figure below shows the TCS device control subsystems, organized in functional categories. Each subsystem includes the required software packages as described in Modules: Subsystem, Packages, Components.
Fig. 5.1 TCS Subsystems Overview#
The description of TCS device control subsystems is included in the sections describing the corresponding system under control in the System Level PDR. The Table below shows a list of these sections. Since this overview document can only convey a limited detail, some design features have been omitted. However they are available in the subsystem level preliminary design review documents.
