For clarification of the TDoA functionality, we use the Vision Simulator program (Simulator) to develop the single screen interface as shown in Figure: TDoA Graphical User Interface. Although the simulator does not understand and respond to all Monitor SCPI commands, it does respond to the complete sub-set of commands that Vision uses.

Typically, a map is loaded from an existing user file. The TDoA Application Graphical User Interface provides the approximate location of the simulated monitors along with a series of locations that are used to simulate RF sources. These RF source locations can represent:
