 The GroundSystem directory contains the new Ground System project for the cFS, that incorporates the main window to launch commands and telemetry systems, and other utilities like FDL/FUL and FT managers to send and receive files. The main window runs alongside the Routing Service (`RoutingService.py`). The Routing Service handles all incoming data and publishes (PUB/SUB) the data to specific ZeroMQ channels so that the different ground system utilities can receive (subscribe) only the desired data.
