Positioning

Navi-Sailor 3000 automatically provides the navigator with all the necessary information:

current ship position and motion vector;
reception of information from the radar/ARPA and handling of radar targets;
data obtained from other connected navigational sensors;
AIS data;
display of the ship contour as per the set parameters and chart scale.

Navi-Sailor 3000 can save several schedules for proceeding along one and the same route. In the network configuration, there is a capability to exchange route data between several interacting Navi-Sailor systems.

Information on Chart Objects

Navi-Sailor 3000 allows to obtain information on all the navigational objects plotted on a vector chart such as lighthouses, buoys, beacons, depth contours, areas, dangerous objects, etc.

Information from Databases

Navi-Sailor 3000 users have access to the following Transas Databases containing information for correct and accurate calculations which permit fuel consumption to be reduced and the passage time to be optimised:

tides and tidal currents;
seasonal surface currents;
weather data.

Routes

Route Planning Capability

Flexible generation and editing of the passage route (graphic and tabular). There are two types of sailing between waypoints (WP`s) (Rhumb line, Great Circle).

Capability to make route schedule calculations taking into consideration:
- weather;
- surface currents;
- tidal currents;
Transmission of route data from the master station to the slaves (in the case of the network ECDIS version).
Printing out of route table.

Route Checking

The mode of checking the route for the proximity of dangers to navigation is realized according to the set of safety parameters defined by user. This mode provides the capability to edit the route at the same time.

Work with Multiple Routes

Simultaneous loading of several routes for viewing and comparing.
Setting up of the active route.
Fast search of the active route on the chart.

Route Autozoom Mode

While sailing along the monitored route, the Navi-Sailor provides AutoZoom functionality which enables the automatic increase of scale as the next waypoint is approached.

Route Monitoring

Constant display of own ship position and motion vector.
Providing of data on the ship position relative to the plotted route.
Monitoring of dangerous chart objects.
Reception of information from the connected sensors.
Display of the ship position RMS depending on the positioning sensor in use.
Display of additional route elements (Arrival Circle, XTE, Turn Radius).

Alarms

Navi-Sailor 3000 system generates the following main groups of alarms:

anti-grounding – approach to dangers to navigation, dangerous depth contours and small depths, approach to special areas;
chart areas – alerting about the approach to line and area type objects on vector electronic charts;
route – ship’s deviation from the route, approach to a WP, passing of the last WP;
target/radar – events related to targets and sensors passing target data to Navi-Sailor;
AIS – this group of alarms is used in operation with various types of AIS transponders (UAIS, AIS transponder when sailing in the Great Lakes area);
sensors – monitoring of data from the connected sensors.

Electronic Log

With the use of the Navi-Sailor 3000 system on board, all the information is automatically recorded in the electronic ship logbook. Subjects recorded are navigational data, status of connected subsystems, charts in use, alarms and operator procedures. It should be noted that the system operator can enter a record manually and put down weather data and own comments at any moment.

Playback Function

Playback function

The passage recording playback function is in compliance with IEC 61174 requirement regarding 12 hour log and is used for viewing all the details of the past voyage by using the data automatically archived by the system in the process of its operation.

The following voyage playback options are available:

playback of the recorded own ship track and motion parameters;
playback of recorded targets tracks received from the ARPA, AIS and RIB;
playback of the recorded radar picture received from the RIB.

Navi-Sailor 3000 ECDIS Additional Options

Integrated Information from Navtex

Navi-Sailor 3000 automatically reads off messages supplied by the Navtex system, processes them; extracts coordinates, area, transmitting station, topic and other parameters; saves the message to the disk and displays the message mark on the electronic chart immediately after its reception. The automatic alarm is activated upon the entry into the zone received from the Navtex receiver, or at the approach to a single message mark.

Radar Picture Overlaying

Navi-Sailor 3000 can incorporate the Transas radar processor board, which receives a signal from the radar, subjects the received signal to digital processing and forms a data array for overlaying a radar picture on the electronic chart. The use of the radar processor board expands considerably Navi-Sailor 3000 scope of capabilities by adding the following features:

overlaying of the "raw" radar picture on top of the chart;
automatic extraction and tracking of up to 128 targets simultaneously;
recording of the "raw" radar picture onto the computer hard disk.

Owing to the capability to track targets throughout the entire radar operating range, automatic target acquisition and tracking, the Transas radar processor also performs ARPA functions.

Integration with SPOS (Weather and Route Planning Tool)

A new convenient onboard SPOS weather and route planning tool integrated with Navi-Sailor 3000 enables users to receive weather forecasts supplied by Meteo Consult via e-mail. The SPOS permits:

subscribscription to, reception and display of forecasts;
input of route and ship details;
calculations of various route options;
comparison of route generation results;
saving of the best route as voyage plan and its daily updating.

The SPOS has a capability to import routes from Navi-Sailor 3000 or create optimum routes and export them to Navi-Sailor 3000.

3 Steps in Order to Be Always Updated with New Weather Forecasts:

create a subscription order in the SPOS;
send it via the ship’s communication station;
Meteo Consult will process your request and email the forecasts to you every day.

The size of a forecast for one area is about 30 Кb, so even Inmarsat Mini-M could be used without huge extra cost.

Integration with the AIS

AIS transponder interface is implemented in accordance with IEC 61993-2 international standard and takes into account IALA Technical Clarifications on Recommendation ITU-R M.1371-1 (Edition 1.3). Interfacing of this device with the Navi-Sailor produces the following capabilities:

to receive and display data on other targets using the AIS (coordinates, name, MMSI, IMO number, ship’s navigation status, ship’s type and nature of cargo, speed, etc.);
to receive and display additional data transmitted by ships and coastal AIS (aids to navigation, base stations, SAR aircraft AIS targets);
to transmit own ship data (call sign, name, MMSI and IMO number, type of cargo, type and navigation status of the ship, etc.);
to transmit safety related messages to other objects of the AIS system.

Enhanced interface capabilities:

Navi-Sailor 3000 ECDIS AIS interface covers all possible AIS transponders in compliance with IEC 61993-2 Ed.1 requirements;
possibility of full scale use of the Navi-Sailor as an MKD in the case of interface with SAAB R4 AIS;
possibility of interfacing with the transponder via Pilot Plug (Pilot Plug Interface) where the Navi-Sailor is used as the Pilot Personal Unit.

Search and Rescue Operations

Navi-Sailor 3000 allows the creation of a route corresponding to one of the SAR patterns recommended by the SAR Convention:

Expanding Square;
Parallel Track/Creeping Line;
Sector Search.

In addition, Current/Drift correction is available (calculated drift in the search area with the current constant).

Track Control System

The Track Control System based on Navi-Sailor 3000 ECDIS used together with the coordinates (EPFS), course (Gyrocompass) and speed (Log) sensors is intended for keeping a ship on a plotted route on straight legs as well as curved tracks.

The Track Control System is certified in accordance with IEC 62065 standard with the following autopilots:

Navis AP3000 Heading Control System – category C. Track control along pre-planned straight and curved tracks. (final stage of certification);
Raytheon NP2025 – category B. Track control along multiple pre-planned straight legs with assisted turns between legs;
Raytheon NP2025 Plus – category C. Track control along pre-planned straight and curved tracks. (final stage of certification);
Yokogawa PT 500A – category C. Track control along pre-planned straight and curved tracks.

Integration with the autopilot allows the vessel to keep on the plotted route automatically with the minimum participation of a navigator. The navigator’s attention which is usually distracted by route correction or performing turn manoeuvres, remains focused on the external navigational conditions.

The Track Control System, like Navi-Sailor 3000 ECDIS is type approved by Det Norske Veritas and meets the IMO MSC.74(69) Annex 2 and Standard IEC 62065 requirements.

Positioning Filter Function

The filter function is used for smoothing GPS/DGPS data based on secondary EPFS (Electronic Position Fixing System), log and gyro data.

The Kalman filter algorithm as well as (D)GPS are implemented for smooth and accurate positioning. Additional weather settings are available for compensation of yaw and sway.

The filter includes monitoring and alarm capability for the control of filtered and raw data divergence in a graphical form and as an indication.

The function is applicable to ships with speeds of less than 30 knots.

The system provides a convenient mean for plotting pre-planned and temporary routes (tracks). All the necessary alarms and indications warn the user of a critical situation.
