Radio Equipment and Systems (RES) ElectroMagnetic Compatibility (EMC) for Maritime Mobile Earth Stations (MMES) Operating in the 1@5/1@6 GHz Bands; Providing Low Bit Rate Data Communications (LBRDC) for the Global Maritime Distress and Safety System (GMDS
This European Telecommunication Standard (ETS) covers the assessment of Inmarsat-C Global Maritime Distress and Safety System (GMDSS) and Enhanced Group Call (EGC) Ship Earth Stations@ as defined by the International Maritime Organization (IMO) to be used for Low Bit Rate Data Communications (LBRDL) in the GMDSS@ in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions for the enclosure port of the radio equipment are found in the related product standard ETS 300 460 [11] for the effective use of spectrum. This ETS specifies the applicable EMC tests@ the test methods@ the limits and the minimum performance criteria for Ship Earth Stations for the maritime mobile service operating in the Maritime Mobile Satellite Service (mmss) bands. The ElectroMagnetic Environment used in this ETS to develop the technical specifications encompasses the ElectroMagnetic Environment on board ships as identified in EN 60945 [13]. The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus in maritime environments. The levels do not cover extreme cases which may occur in any location@ but have a low probability of occurrence. Compliance of radio equipment to the requirements of this ETS does not signify compliance to any requirements related to the use of the equipment (i.e. licensing requirements). Compliance to this ETS does not signify compliance to any safety requirements. However@ it is the responsibility of the assessor of the equipment that any observations regarding apparatus becoming dangerous or unsafe as a result of the application of the tests defined in the ETS@ are recorded in the test report. This ETS is based on the consideration and guidance as given in ETR 238 [12].
