1.1 An introduction to terms
This section describes the terms in vessel/vehicle surveillance that
are needed to understand the role of Inmarsat and T&T in VMS.
The most important terms used in VMS are Land Earth Stations
(LES), VMS Data Network Id (DNID) and Member numbers .
Figure 1 shows a typical transmission path of a position being
transferred from the Inmarsat-C transceiver in a fishery vessel to
the vessel surveillance centre. The same path applies - but in the
opposite direction - for commands send to the vessel.
