General data

The Navi-Sailor 3000 has been designed in compliance with the IMO requirements for Integrated Navigational Systems (draft IEC61924). The simulator is used to train students in the field of navigation and ship handling using a network system.

In the networked configuration, it is possible to share route information between several interactive Navi-Sailor systems. When this function is activated, a route collection on a secondary workstation is compared with the route collection of the Master workstation.

Then the unique files present on a workstation are copied to all the other stations in the network. In the case of several routes with the same name, the most recently modified route is selected and copied onto other station(-s).    

The system components are: a master station (instructor station) and two secondary stations (bridge).

The master station allows to create scenarios inside coastal waters or offshore, to simulate different sea states and different visibility conditions.

The system incorporates all the functionality of ECDIS system. Three variants of radar ARPA create a real radar picture on a display close to conning ship display.

The global database on the world's seasonal surface currents consists of 480,000 monthly surface current vectors.

The global database on tidal water levels refers to 12,000 points. Levels in each point are calculated from eleven harmonicas. The same database on the Sun and Moon ephemerides is used.

The database on tidal currents contains data on 70,000 hourly vectors. Tidal current data are provided for 12,000 points. Tidal current levels in each point are calculated based on 11 harmonicas. There is a separate astronomic database on the Sun and Moon ephemerides up to the year 2005, which is also required for calculations.

Transas Navi-Sailor is provided with a special editor module that allows voyage route planning using the simple movement of the cursor through the chart to point at required waypoints. This function allows the creation of a route plan from the point of departure to the point of arrival including up to 999 waypoints. The Route Planning also checks for the presence of navigational dangers when under way such as safe depth and isolated dangers. The Route Plan table contains detailed information on the suggested route(-s) including each waypoint co-ordinates, distances and courses between waypoints, total route length, ETA and much more. Route Plan calculations take in to account relevant weather and tidal information. 

Navi-Sailor incorporates a comprehensive Route Monitoring function. This program runs concurrently with other operation modes, and automatically provides the navigator with the most important voyage information including: primary and secondary ship position, ARPA target information, vessel track, display of the ship's contours in the chart scales comparablewith the ship's dimensions, information on dangerous objects on the chart, and data from interfaced sensors.
The system allows to save routes and to load them again after a time. For visual and audio notification to the navigator about the vessel exceeding pre-set limitations for the calculation of the ship's current position, it is necessary to set indicators in the ALARM sub-menu of the Route Monitoring mode.

Electronic charts

Navi-Sailor 3000 works with the following chart formats:

• S-57 - official charts issued by national Hydrographic Offices
• ARCS - by UKHO
• NDI/BSB - by NOAA (USA) and CHS (Canada)
• Seafarer - by the Australian Hydrographic Office
• TX-97 - by Transas Marine
• DNC VPF - by NIMA

Navi-Sailor 3000 has a facility for Multi-Chart loading providing simultaneous display of up to 6 charts of different formats. hart correction is ensured using a CD or the website.
