Danphone has developed, manufactured and installed advanced radio communication equipment and complete systems since 1990. We are experts within maritime communication technology, specializing in VHF, MF/HF and NAVTEX.
Danphone’s GMDSS Coastal Radio System is a flexible, IP-based radio communication system primarily for coast stations, ports and off-shore installations and designed specifically to comply with ITU, IMO and international maritime specifications.
Danphone GMDSS coast stations for VHF and MF/HF are delivered in compliance with relevant IMO and ITU specifications, including DSC, voice and data logging, and interface with landline telephones. The system features IP-network infrastructure, Voice over IP and remote control via touch monitors.
Danphone's GMDSS Communication System has been specifically designed with GMDSS in mind and thus complies to the relevant
international requirements and recommendation including the need for reliable 24/7 operation.
Incorporating VHF base stations, MF/HF radios, remote-control via touch screen computers and Danphone's renowned Network Management System the GMDSS Communication System can be configured and customized to suit all requirements. From a simple single-radio setup to a complex national system with multiple operator and radio sites installed at various remote locations, this communication system provides the complete solution.
One operator can operate several radios simultaneously with Danphone's Voice User Interface and cover a large graphical area of responsibility as well as the ability to monitor and control each individual radio. Duplication of critical units ensure failsafe solutions and minimising single point of failure.
Danphone's installations include equipment for the coverage of all three sea areas (A1, A2 & A3) with high performance VHF and MF/HF radios. These radios are currently ensuring complete and reliable communication in over 30 coastal radio installations worldwide.
Danphone incorporates state-of-the-art VHF and MF/HF radios in the GMDSS systems with a focus on explicit quality and functionality supporting safety-first policy. Using third party MF/HF radios, Danphone can provide solutions with 125W - 1kW transmitters and multiple receivers. The MF/HF radios operates in the marine bands from 1.6 - 30 MHz. The MF/HF transceiver covers sea area A2 and A3. Sea area A4 requires HF radio with DSC.
VHF BASE STATION RECEIVER
The VHF Base Station Transceiver is specically designed to operate in the marine VHF band. The new VHF radios come with an option of two receivers and built-in DSC modem for continous automated supervision of CH70. The transceiver connects with LAN, antenna and power supply. In addition to VoIP and remote-control over IP, the VHF radio allows for local control via optional display and handset.
VHF RACK MOUNT
Danphone's own VHF rack mount covering sea area A1 is built in-house to fit the customers need. It can be employed in small as well as large radio systems. With up to 75 Watt continuous output power each radio can be set up to any international marine channel either full duplex, semi duplex or simplex operating mode. The radios meet European ETSI and American FCC standards with respect to RF performance and EMC, and are manufactures with quality, cost efficiency and flexibility utmost in mind. The Danphone Communication System guarantees clear and reliable voice communication as well as continuous DSC watch on the distress channel.
Danphone's user interface focuses on easy operation. Visual and audible alarms are automated and the system will automatically prioritize distress messages for fast response.
The Danphone operator software has an intuitive graphical interface and the workstations are touch monitor PC terminals configured as clients logged onto the system server via LAN. The control and Voice Switch Software is installed on the server. User applications are installed on each individual operator terminal.
VOICE USER INTERFACE
The Voice User Interface allows transmitting of voice recorded messages. It provides a complete overview of all radio sites including thier current operational status and configuration. Furthermore, the display shows a control panel with number keypad for channel configuration and facility keys for broadcast transmissions and scanning. Touch screen operation ensures an efficient service.
DIGITAL SELECTIVE CALLING
Digital Selective Calling (DSC) ensures fast and reliable response to vessels in distress. The DSC Inbox lists all unanswered DSC messages in order of priority and time. Distress messages are displayed in red, safety messages in yellow and routine messages in green. Danphone's DSC interface prioritizes all distress calls for quick response and is compliant to: ITU-R M. 493-14, ITU-R M. 821-1, ITU-R M. 1080. It ensures full logging of all received and sent messages for future references.
Danphone's Network Management System for GMDSS gives the user a complete graphocal overview of the entire network as well as the ability to monitor and control each individual transceiver. The system enables remote controlled monitoring, system and device settings and even switching of transceivers and coaxial connections, e.g in the event of failure. All kind of events, such as errors, alerts, acknowledgements, new system and device configurations etc. are automatically logged in the system database.
The system features IP network infrastructure, remote configuration and monitoring via either touch screen or keyboard for easy operation. Each radio has its own status page showing operating temperature, transmitter power, reflected power, etc. Minimum and maximum values of these parameters can be adjusted to initiate external alarm handling.
The color on the icons show green for OK, yellow for warning and red for error, which makes it simple to get an overview of the network. Automated visual alarms displayed on the map of all site locations, indicate warnings or failures along with complete log of all events.
GMDSS (Global Maritime Distress and Safety System) is an internationally agreed-upon set of safety procedures, communication equipment and protocols used to increase safety at sea and make it easier to send aid to ships in distress. GMDSS is defined in the SOLAS convention.

GMDSS consists of several integrated systems, some of which are new, but many of which have been in operation for many years. The systems are intended to perform alerting and position determination of vessels in distress, search and rescue coordination, maritime safety information broadcasts, ship-to-shore and ship-to-ship communications.
