NAVTEX is the international automated safety service for broadcasting meteorological warnings, navigational statusses and urgent Maritime Safety Information (MSI).
The Danphone MSI NAVTEX Transmitter Solution is scalable and can be customised to suit all requirements - both from a single-transmitter setup to a complex national system with multiple operators and transmitter sites installed at various remote locations.
Danphone is committed to the development of NAVDAT (NAVigational DATa) in the 500 KHz band, and will provide NAVDAT systems to support the ITU and IMO standardization and overall implementation plan to customers.
With more than 40 NAVTEX transmitters delivered since 2007, Danphone is truly a leading supplier of NAVTEX systems worldwide.
The Complete Solution has a software suite to encompass all management, system and operator functions and processes
from intuitive user interface focusing on easy operation and simple integrated management.
The Danphone NAVTEX Transmitter System (1kW, 2kW and 3kW transmitters) is specifically designed for complete reliability, scalability and easy management, in accordance with the IMO NAVTEX Manual. Danphone are experts in developing systems customized to fit the natural environment for optimal transmission. The NAVTEX Transmitter Solution is prepared for integration with Danphone Martime GMDSS Communication Solution and optional integration with other external systems.
Over the past 15 years, the NAVTEX Transmitter Solutions system has been perfected to withstand harsh environments. The systems have been tested and proved in a great variety of harsh environments from the icy conditions in Greenland to the hot humid areas of India. The server free architecture ensures transmission of compiled messages even if the network is down.
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.
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.
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.
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.
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.
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.
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.
