SN-5703



SN 5703 is the consumer's navigation equipment (CNE) of GLONASS/GPS/GALILEO systems; it contains built-in receiver of differential corrections and the functions of controlling external complexes and communication systems for the purpose of monitoring and informational-navigational support of river vessels and sea vessels.
SN 5703 is the main device of shipborne subscriber’s set of the vessel traffic monitoring system. The basic design version of the device may be used as part of the equipment of dispatching center (DC) as the response device coupled with the dispatching system used at the DC.
SN 5703 is intended for usage on river vessels and sea vessels as CNE of global satellite navigation systems with a receiver of differential corrections of maritime differential subsystem, and also as the main device for vessel traffic monitoring system.
The device has connections with ECDIS, shipborne sensors, controller of shipborne sensors, shipborne LAN.

 

• Determination of vessel navigation parameters:
   — current coordinates in the chosen coordinate system;
   — current time and date;
   — speed over ground;
   — course angle.
• Formation and transmission of short text messages and coded messages to the dispatch center (one or several).
• Possibility of transmitting data for correction of electronic charts.
• Adjustable priority and modes of communications systems used for data transfer.
• Data exchange with ECDIS for displaying and formation of service messages in the monitoring system.
• Informational interaction with AIS when using ECDIS.
• Possibility of working with dispatch centers from different vendors (data exchange interface is required).
• Design version with satellite compass function is available

SN-5703 is a single-unit device in a casing with the necessary connections for antennas, communication equipment (including short-wave/ ultra-short wave), external visual displays, ECDIS, controller for interfacing with vessel sensors, power supply and headset.
If no external systems are connected, the device is used as a tracker with built-in GPRS modem.
