Navtex system


Marinsys-Navtex system

The Marinsys-Navtex System is based in a Server/Client architecture that allows the maximum reliability, flexibility and scalability by using independent units. It has an efficient intercommunication between the units for a limited consumption of broad band in order to guarantee the operation of the Navtex transmission system regardless the communication availability between the units and centres.

The four important characteristics that distinguish the Marinsys-Navtex system are:

A single manager can operate up to 8 coastal stations, with the possibility of working in the 490KHz, 518KHz and 4209.5KHz with automatic control of all its parameters.
The system has in each coastal station a transmissions local controller (Navtex remote control) with all the information stored that comes previously from the Navtex operation manager in order to establish automatic and independent transmissions of the operation manager and its communication. This avoids the communication breakdown problems between the control center and the coastal station.
The system can be configured with independent transmitters for each of the operation frequencies or with a single Invelco transmitter that allows operating in the three frequencies.
Possibility of redundant communication between the operation manager and each coastal station. Up to 3 different IP channels of communication.

The main units of the system are:

  • Automatic Navtex coordinator workstation (ARM-78)
  • Automatic Navtex operator workstation (ARM-77 with Marinsys Navtex Emissions Manager software)
  • System control & monitoring operator workstation (ARM-79)
  • Navtex Remote Control (MSRC-400-A).
  • FTP server (MSFS-1132).
  • Navtex Transmitter (MSM-7xx-x series /SDR TECHNOLOGY, 490/518/4209.5 kHz, 1/2/5 kW).
  • Tri-channel Navtex receiver with coastal function 
The Navtex Transmission System has the possibility of simultaneously manage the transmissions in 518 KHz, 490 KHz and 4209.5 KHz frequencies of one (1) to eight (8) Navtex Transmission stations.
Each station is defined in the system individually with its own characteristics (station code, operation frequencies, schedules (time slots), transmitters, power levels, etc.)
