Electronic Chart Display and Information System
The Electronic Chart Display and Information systems (ECDIS)
are extremely efficient mean of navigation, which significantly
reduce the workload of the officers on watch, thus allowing
them to devote more time to the observation of the surroundings
and to the navigation of the ship. The ECDIS is unique means
of navigation, particularly as far as the automatic activation
of the alarm signal upon the detection of dangerous objects
marked on the chart is concerned. Considering that nearly
50% of all accidents are the result of navigational errors
(this figure varies significantly depending on the region),
the cost of the cartographic systems is undoubtedly justified.
SAFENAV-3
It is a shipboard system. The system meets the IMO standard
for ECDIS and the standard IEC 61174. SAFENAV-3 can use the
official electronic charts, produced by hydrographic offices
in S-57 format of third version as well as the CM-93 electronic
charts of third version from the company C-MAP compatible
with S-57/3 format. The library consists of more than 14000
electronic charts, covering all regions of World Ocean and
majority of navigational waterways. Such combination permits
to use the ECDIS immediately after installation if the official
charts for the areas are absent.
SAFENAV-3 permits to present the electronic charts both: in
S-52/3 format and the traditional paper charts in IHO INT1
standard.

SAFENAV-3 permits to work at full the route:
- Graphical and tabular (rhumb track and great circle) route
plotting
- Schedule calculation with allowance of anchorage in intermediate
ports and the amount of rise in critical areas (the C-MAP
database presents tide information at more than 3000 points,
what allows to calculate automatically the variations of
sea level on the fixed date)
- Automatic route safety check according to detailed, updated
charts
- Chart lifting in surrounding of course applying the user's
special objects
- Plotting of points, when approaching to which the system
will signal to navigator for example: lighthouse beam passing,
the approach to point of pilot meeting, the mandatory report
when approaching to regulated navigation area
- Possibility of synchronous demonstration of chart and
three dimensional model of sea bottom permits to class the
characteristics of narrow passage
|
During the navigation SAFENAV-3 plots a route, provides
the ships control, determines and displays dangerous/safe course
sector according to electronics charts data, alarms when approaching
to dangerous areas or areas, closed to navigation , alarms when
the ship swerves out the route, approaches to turn / control
point. The navigator can solve the cartometric problems, adjust
the cursor for tracking the range and bearing to them, the radar
targets presentation, diagram of depth, echo sounded. The system
permits present simultaneously in different windows the water
area in different scales, three dimensional image of sea bottom
with ship's check point, the curve of sea level variations,
the navigation data and the information to intended route motion,
the system state indicators, the cartographic objects information.
System functions and possibilities:
- Route planning
- Route safety check
- Route monitoring
- Automatic ship tracking
- Logging and recording of targets (optional)
- Nautical chart catalogue
- Base, Standard and Full display of Playback of recorded
navigational electronic charts
- Mariner's objects database
- Anti grounding and other Navigational alarms, required
for ECDIS
- Colour palette, selectable by operator
- Electronic Range/Bearing cursor
- Navigational sensor's and manual drift and current input
- Playback of recorded navigational situations
|
The SAFENAV-3 system can receive information from the following
type of sensors:
- GPS in formats RMC, GLL and VTG
- Loran C
- Magnetic compass
- Gyro, north seeking
- Gyro, non-north seeking
- Doppler or correlation speed log
- Electromagnetic speed log
- Mechanical speed log
- Pressure speed log
- nmea Autopilot output

NTS-Pro 4000 (ECDIS)
The NTS-Pro 4000 (ECDIS) is a PC based simulator of electronic
chart display and information system. ECDIS simulator has
been designed to meet the growing need for professional training
of ECDIS operators.
The simulator allows a mariners to achieve the
following:
- Demonstrate the proper use of the ECDIS equipment, including
the use of navigational functions associated with route planning
and monitoring; the ability to select, display, and interpret
relevant information, and knowing what proper action to take
in case of malfunction.
- Acquire a knowledge and functional understanding of the basic
principles governing ENC data and its proper display in ECDIS;
- Be aware of ECDIS-related limitations, particularly those
associated with errors of interpretation, over-reliance, and
complacency.
