| LSF II is a high-speed boat of landing
craft, air cushion which will be introduced to reinforce
landing forces of RoKN. Many countries have developed
and been operating these boats. LSF II is a project, which
is locally developed and manufactured on the basis of
the LCAC model of US NAVY. LCACs under operation by US
Navy were developed in 1984 and have been delpoyed so
far. |
 |
US Navy is improving engines of LCAC and modernizing onboard
equipments towards SLEP version. iCAMs is a solution which is
developed to be mounted onboard LSF II. GMB has contracted to
supply iCAMS to RoKN in cooperation with Sperry-Marine an affiliate
of Northop-Grumman. It is mounted and being operated onboard
LCAC SLEP of US Navy. iCAMS integrating the existing CAMS in
use is developed to allow for efficient operations. (The above

CAMS consist of UKB, iCAMS, INS,
CDR and MPAS that is linked with redundant high speed network
to maintain communications capability and to integrate operations.
Every information is delivered to operators through color
displays as combined and integrated. Operators give commands
to operate the boat by using 4X4 keyboard of UKB, trackball,
operating handle in control room and pedal, etc. Also, MAPS
(Mission Planning and Analysis System) provides information
which is required for operations missions and then every information
will be shared by navigator, operator and engineer to allow
for efficient operations.

| INS (Integrated
Navigation System) |
The LSF II Navigation System consists of navigation sensors,
displays and MMI, integrated with a Navigation Processing Unit,
which consists of a Navigator Computer and Operator Computer.
The system integrates the LSF II navigation sensor data to provide
graphical navigation displays for the craft navigator and operator.
| CAMS (Control
and Alarm Monitoring System) |
The CAMS consists of dual-redundant processing computer units
that provide for vessel control that Engineer's display, Operator's
gauge display, Operator's Navigation, CAMS display, Sensor Interface
Unit (SIU) control loop processing, and FADEC interface processing
A number of controls and indicators at the LCAC engineer and
navigator stations will be replaced by the UKB. One UKB will
be installed at the navigator's stating and one UKB system
will be installed at the engineer's station. The function of
the UKB is to provide a man-machine interface to CAMS, replacement
Communication System, and replacement Navigation System. The
UKB utilizes the CDR for the recording/loading of mission related
navigation and communication data, and the recording of digitized
radar video and digitized audio, craft/engine sensor data and
alarm/status data.
| CDR (Common
Data Recorder) |
The CDR is network addressable PC-104 computer with a removable
hard drive used to store and retrieve mission related data.
CDR will contain data that during the navigation system's initialization
routines, radar data, and non-radar data that is continually
streamed to disk by both the navigation and engineering systems
during mission execution.
| MPAS(Mission
Planning and Analysis System) |
MPAS is an application program that executes on the LMSS (LCAC
Mission Support System). The application program supports off-craft
pre-mission planning and post mission analysis. |
