The server free architecture ensures transmission of compiled messages even if the network is down.
NAVTEX NETWORK MANAGEMENT SYSTEM
SIMPLIFIED NETWORK MANAGEMENT AND CONFIGURATION
Danphone's Network Management System provides the ultimate overview of site locations and simple network management of the entire system. It enables monitoring and configuration of each individual transmitter to avoid failed transmissions. For a complete overview the system provides all relevant data including message transmissions, temperature and forward and reflected power readings. In case of failure, the system offers visual and audible alarms.
KEY FEATURES
- Monitoring and configuration of transmitters
- Automatic or manual active/standby transmitter switch-over
- Complete logging of all events
- Simple Network Management Protocol (SNMP) Interface
- Visual indications of warnings and failures
- Audible alarm upon request
- Multiple-level password protection
NAVTEX USER INTERFACE
INTUITIVE USER INTERFACE
The NAVTEX User Interface is intuitive and enables easy preparation and scheduling of messages and automatic transmissions of these. Danphone's NAVTEX Transmitter works independently of network functionality. It ensures messages can be sent even if a reverse power fault is observed. The fail-safe transmission is ensured by planned messages generated by remote control at preselected times, frequencies and output power.
AUTOMATIC TRANSMISSION
The operator can choose to schedule messages within selected time-slots or transmit urgent information immediately. All messages are automatically transmitted and logged. The interface is operated by either touch screen or keyboard.
COMPLETE OVERVIEW
The Danphone Interface supports easy editing and quick action in urgent circumstances by listing messages according to time and date. Messages are seperated by: overview of all transmissions, active messages, sent messages and draft messages.
NAVTEX UNICODE
Danphone has developed an unique innovative solution to transmit NAVTEX messages in non-latin character set - the NAVTEX UNICODE.
The solution uses the IT-based UNICODE standard and enables secure error-corrected transmission/reception of NAVTEX messages. The NAVTEX UNICODE system supports more than 200 local languages. Transmission of messages written in a local language will increase understanding of the content and enable faster response time to warnings.
KEY FEATURES OF THE DANPHONE NAVTEX SYSTEM
- IP network infrastructure (IEEE 802.3)
- Transmission of compiled messages even if the
network is down - Supports 518 kHz and 490 kHz transmissions
with any local character set in any language - Storage of all transmitted messages

Danphone specialists
NAVTEX TRANSMITTERS
SCALABLE WORLDWIDE INSTALLATIONS
The Danphone NAVTEX transmitter is developed and produced at Danphone's factory. It transmits NAVTEX messages in any local language on 490 kHz and 518 kHz. In case of reverse power fault, the transmitter continues to send messages by automatically reducing forward power to a safe level.
The transmitters are designed for standard 19" rack mount and can be installed in seperate cabinets or stacked together in one cabinet. A standard setup comprises two redundant NAVTEX transmitters and single-phase power supply unit.
The output from the transmitter may be connected to Danphone's automatic tuning unit in order to match the transmitters 50 Ω output impedance to the antenna's.
WHAT IS NAVTEX?
NAVTEX is an internationally coordinated and automated direct-printing service for promulgation of navigational and meteorological warnings, meteorological forecasts and other urgent information to ships.
NAVTEX is a component of the Worldwide Navigation Warning Service (WWNWS) defined by the IMO. NAVTEX is also a major element of the Global Maritime Distress Safety System (GMDSS) mandated by the international convention for the Safety of Life at Sea (SOLAS) dating back to August 1993.
The world has been divided into a number of NAVTEX areas, which then each are managed by a number of centres that controls a number of NAVTEX stations.
