1 Scope
This European Telecommunication Standard ETS specifies the minimum performance requirements,
technical characteristics and conformance testing requirements of a satellite Emergency Position
Indicating Radio Beacon (EPIRB) operating in the Inmarsat geostationary satellite system as described in
Regulation IV subclause 7.1.6 of the 1988 amendments to the 1974 International Convention for Safety of
Life at Sea (SOLAS) [2].
The requirements of this ETS are in addition to the requirements of Inmarsat-E System Definition
Manual [11].
This ETS comprises the relevant requirements of the Radio Regulations [1], International Maritime
Organisation (IMO) Resolutions A.658(16) [3], A.661(16) [4], A.662(16) [5], A.689(17) [6], A.694(17) [7],
A.702(17) [8], ITU-R Recommendation M.632-2 [9], and Regulation IV-7.1.6 of the 1988 amendments to
the 1974 SOLAS Convention [2].
This ETS covers the following categories of satellite EPIRBs and release mechanism:
- satellite EPIRB with position updating from the ship's navigational installation and with an integral
9 GHz radar transponder;
- satellite EPIRB with position updating from an integral facility for automatic position updating;
- additionally, the satellite EPIRB may include a 121,5 MHz homing transmitter.
To further meet the requirements of Regulation IV subclauses 10.1.4.3 and 10.2.3.2.2 of the 1988
amendments to the 1974 SOLAS Convention [2], with regard to remote activation for both categories, an
additional remote control unit for remote activation and for feeding the satellite EPIRB with "nature of
distress" information is specified.
