scope:
This European Telecommunication Standard ETS covers the assessment of Mobile Earth Stations (MESS) and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC).
Technical specifications related to the antenna port and emissions from the enclosure port of the equipment are not included in this ETS. Such specific technical specifications are found in the relevant product standard.
This ETS specifies the applicable EMC tests, the test methods, the limits and the minimum performance criteria for MES'S providing Low Bit Rate Data Communications (LBDRC) using satellites in Low Earth Orbit (LEO) and operating in frequency bands below 1 GHz, as defined in ETS 300 721 [3], and ancillary equipment.
In addition to the technical specification of this ETS, there may be published in the Official Journal of the European Communities (OJEC) references to Harmonized EMC standards that apply to the products covered by this ETS in their own right, for example EN 61000-3-2 and EN 61000-3-3 (power frequency harmonics and voltage fluctuation).
The environment classification used in this ETS refers to the environment classification used in the Generic Standards EN 50081-1 111 and EN 50082-1 [2], except the vehicular environment class which refers to IS0 7637 Section 1 and 2 [4] and [5]. The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus at residential, commercial, light industrial and vehicular environments. The levels, however, do not cover extreme cases which may occur in any location but with a low probability of occurrence.
This ETC may not cover those cases where a potential source of interference, which is producing individually repeated transient phenomena, or a continuous phenomenon, is permanently present, e.g. a radar or broadcast site in the near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference, or the interfered part, or both.
Compliance of a MES to the requirements of this ETS does not signify compliance to any requirements related to the use of the equipment (¡.e. licensing requirements).
This ETS is based on the considerations and guidance given in ETR 238 [14].
