Getting Started - Ground Station
================================

The Ground Station as a whole allows all the different systems and hardware to
communicate with each other. The Ground Station has four main components including:
	* Command Line Interface (CLI)
	* Graphical User Interface (GUI)
	* Frontend
	* Backend
Both the CLI and GUI are user interfaces. The GUI uses all the same commands and the 
CLI but has extra functionality. The GUI shows the controls graph, provides extra
navigation help, and will soon support real time graphing of the data. The Frontend
does all the reading from and writing to the backend via a socket connected to the 
backend. The backend is primarily a server that manages all connections and where all
data passes through between the VRPN (Camera System), the quad, and user interfaces.
**Figure 1** shows the main components and their interaction. Both user interfaces use
the frontend to manage the writing and parsing of return messages from the backend.
