The FCS may be a stand alone application maintained by the motor carrier or an internet service running by the supplier of the system. The FCS usually includes a database in which all vehicle positions and messages are stored.

Usually, the VS is equipped with a simple input device allowing drivers to send predefined status messages. Drivers may add simple content, e.g., numeric values, but usually cannot enter arbitrary text. Besides the messages sent by drivers, some VS can also automatically submit messages, e.g., the vehicle’s position, data from sensors in the cargo
