18. Common Reference System
(Multi-workstation mode)
18.1
Introduction
A system is comprised of one or more Workstation(s) and it is configured as follows:
•
Single workstation
•
Multiple workstation (for example, navigation workstation and planning station)
•
Multiple workstation (for example, navigation workstations)
An access server takes care of information shared inside the system to keep workstations consistent within the
common reference system concept. The access server also monitors if a workstation has a right to make certain
actions (for example if a workstation has usage rights to change monitored route for the system).
The common reference system concept includes the following features:
•
Shared navigation sensors
•
Shared alarm management
•
Shared chart databases for S57 (ENC) and ARCS
•
Shared databases for routes, user charts, manual updates and pilot data
•
Some user selections are shared (for example safety contour), while some other user selections are defined
separately for each workstation.
•
User selections used for route planning are separate for each workstation
The Installation parameters of the system define if the system consists of more than one workstation and in which
the access server is running. For further details see the service manual.
