3.2 Service Area Description
The Service Area (SA) is a container including all of the critical elements necessary to calculate
coordinated areas, determine operational or non-operational areas pushing updates and controls
to associated transmission equipment. The perimeter control within the SA is the Service Bounds
(SB) which is a multipoint polygon fence setting the satellite transmission beam area borders.
There are also Coordinated Area Maps (CAM) that if required can set transmit carrier zones
whereby the vessels transmit carrier is controlled to either enable or disable within these
boundaries. ROSS can store hundreds of these Service Areas that define the operating parameters
for each satellite and/or ground based equipment that the vessel requires for normal operation
within any given geographical location.
Each unique SA is created or maintained locally/remotely using the ROSS Configuration Editor
(RCE). The editor consolidates database elements into a single structure which is downloaded or
uploaded to the ROSS. The ROSS incorporates a file manger that labels each file element
through logical renaming appending each file with a sequential number grouping them all into a
SA. Example SA, the ACU command information sets the base reference with modem
configuration file(s), SB(s) which are then grouped together with a unique number. The SA
number is irrelevant to the user as it is assigned at the time of reception during uploads to ROSS.
The number assignment is only relevant to ROSS as container grouped database information.
The SA example figure 2 depicts the structure of two separate SA binding list elements together
into a distinct area. This grouping is shown with only one SB per SA and two shared CAM's,
however multiple SB's can be linked into a single SA. Configuring SA's is described in much
more detail in the Configuration section of this manual.
