ROSS
Each Service Area is associated with a number of required files that when combined create an
overall operational SA. After creation of a SA it is processed (edited, uploaded) by highlighting
(click select) the row as shown.
All created SA groups are uploaded and also stored locally for retrieval further editing. When
saving the newly or edited file, assign a logical name for easy association to editing ROSS unit.

ROSS Configuration Items
There are four important data items that the RCE can edit. These items are necessary for ROSS
to operate:
1. Service Area(s), consist of a collection Service Bounds which are geographic areas
that define the operating zone. Service Areas (SAs) can contain one or more Service
Bounds that operate under a specific satellite beam.
2. Service Bound(s), as previously stated each Service Area can contain one or many
service bounds (SB). If ROSS detects that a vessel has moved into a SB that is in
another SA, ROSS initiates a satellite handoff operation into a different configuration,
e.g. hub, satellite, TDM carrier or all combinations. SB are polygonal areas defined
by latitude/longitude coordinates which cover satellite and/or hub transmissions that
are overlaid bridging the communication hops between service connections. Starting
with VMS 3.7.x and ROSS 1.2.0.x, Service Bounds can also provided Advanced
Switching modulation table to optimize spectral efficiency on a per Service Bound
basis.
3. Modem Configuration sets all the parameters in the modem and is associated to a
SA transforming the communications to match entry points of hub, satellite, TDM,
STDMA controller and/or all.
4. Coordinated Area(s), like the Service Bound, a coordinated area is collection of
geographic zones defined by coordinates. Unlike the SB, the coordinated areas are
used to indicate special use cases such (1) inhibiting a transmission within an SB, or
(2) overriding shoreline transmission exclusion. Section 6.1.10 provides more details
on using Coordinated Areas.
Note the ACU parameters are the assignment of antenna pointing information for that
SA and are the base starting point of configurations.
