System overview
The SAILOR 6120/30/40/50 mini-C system
The Inmarsat C satellite network is the link between the mini-C system and
the destination office. It uses four geostationary satellites to cover the
world. For each satellite there is an NCS, Network Coordination Station,
handling registration of the mobile unit (in this case the SAILOR 3027) in
the Inmarsat C system.
Each NCS is associated with a number of LESes, Land Earth Stations, which
handle the transmission between the mobile units and the destination
office.
The SAILOR 3027 can work as a standalone system automatically
transmitting data on the Inmarsat C network, or you can connect alarm
buttons and/or a computer through the SAILOR 6194 Terminal Control
Unit.
