FELCOM 30/50/70 are FURUNO's new Inmarsat FLEET F33/55/77 Mobile Earth Stations.
This series provides quality fax and telecommunications, and data communications such as e-mail and Internet accesses in places where the coverage for conventional mobile phones or radio networks is not available. In the data communication service, this series provides high-speed data transfer with low communication fees by using ISDN and the unique MPDS(Mobile Packet Data Service), newly introduced in Fleet MES.
This series basically consists of an antenna, a communication unit and a handset.
The palm-sized handset is identical for all three FELCOM models, and it is used to set all the configuration settings as well as dialing for telecommunications. The communication units come with a variety of interface ports to link with PCs as well as communications equipment. They have terminal blocks and RJ-45 connectors for ISDN and connectors for RS-232C, RS-422 and USB. Connected to an IP router, several PCs can share the Internet connection via the MPDS Service.
This series provides SIM card function. This function makes it possible for crew members to make phonecalls in greater privacy. The calls are billed to the owner of the SIM card when it is used. (For details, please consult with the service provider.)

Antena stabilization and tracking
This radome contains a helix array radiator with a dish reflector. Antenna stabilization is realized by using the three-axis active method that detects ship's motion with three rate sensors and an inclinometer.
This mechanism allows the antenna to keep pointing to an appropriate satellite while a ship is in motion. Connection between the electronic circuits on the turning section with a parabola and those on the fixed pedestal in the radome is made by an improved rotary joint. A GPS receiver is incorporated in the radome and provides accurate position information to allow the MES to determine whether it is within coverage of a spot-beam as well as to orient the dish to the satellite to be used. This arrangement eliminates antenna rewind, providing uninterrupted communications during a course change of the vessel without heading signal input from gyrocompass.
The communication unit
The communication unit accommodates a variety of ports, ISDN telephone, RS-232 and USB to make itself compatible with other communications equipment as well as a PC. There is no need to have interface units such as a terminal adapter. It is a BlackBox unit and may be installed at any place in the bridge.
Distress alert unit
In case of emergency, by pressing the alert button, a mayday call transmission to the coast station will be initiated. Messages concerning alert transmission and reception are displayed on the standard handset
