17、mmunications, and for Enhanced Group Call (EGC) equipment, as required by regulations IVn, IV/8, IV/9 and IWO of the 1974 International Convention for Safety of Life at Sea (COLAS) 5 as amended, concerning radio communications for the Global Maritime Distress and Safety System (GMDSS). Minimum perfo
18、rmance requirements for the Network Control Facility (NCF) are contained in ETS 300 459 131. NOTE: The only satellite system accepted by the SOLAS convention to provide LBRDC in the GMDSS is INMARSAT-C at the date of publication. For the purpose of this ETS the term “ship earth station“ is used in o
19、rder to align this ETS to ITU terminology. It is defined as a Maritime Mobile Earth Station (MMES) operating in the GMDSS. This ETS is applicable to the following classes of equipment: - Class O: - a stand alone EGC receiver; - Class 1: - a basic ship earth station providing shore-to-ship and ship-t
20、o-shore message transfer only; - Class2: - as for Class 1 but with EGC as an alternative to shore-to-ship transfer using a shared receiver; - Class 3: - as for Class 1 but with EGC using an independent receiver. This ETS covers equipment construction and performance testing. GMDSS requirements and t
21、ests are included where they are supplementary to those contained in the equipment certification required in subclause 5.1. Frequency bands allocated by the Radio Regulations l to the MariMme Mobile Satellite Service (MMSS) are as follows: Requirements are specified in order to ensure the requiremen
22、ts of the GMDSS are met, to protect other users of the frequency spectrum from unacceptable interference, for the purposes of general safety and for the provision of protection of the ship earth station against electromagnetic interference from other systems. 3 Page 8 ETS 300 460: May 1996 ETSI ETS*

30、1 Definitions For the purposes of this ETS, the following definitions apply: ship earth station: A MMES on board a ship, (see clause 1). nominated bandwidth: The nominated bandwidth encompasses all spectral elements of the transmission which have a level greater than the specified spurious levels. T
31、he nominated bandwidth is wide enough to take account of the transmit carrier frequency stability. The nominated bandwidth is within the MMSS transmit frequency band within which the ship earth station operates. The bandwidth of the ship earth station radio frequency transmission is nominated by the
32、 manufacturer and included in the data sheet of the test report. unwanted emissions: For the purpose of this ETS unwanted emissions are those falling outside the nominated bandwidth. performance check: A performance check consists of the following: - for Class O equipment: - reception of a distress
33、priority EGC message; - for Class 1 equipment: - for Class 2 and 3 equipment: - transmission of a distress message; - transmission of a distress message and reception of a distress priority EGC message. The transmission of a distress message is considered to be successful when: - the Special Test Eq
34、uipment (STE) has received the distress message and correctly interpreted it; and the Equipment Under Test (EUT) has correctly indicated to the user, the acknowledgement of receipt of the transmission from the STE. The reception of a distress priority EGC message is considered to be successful when
35、the EUT has printed the message and the appropriate indications are provided to the user that a distress priority EGC message has been received. Special Test Equipment (STE): Specific equipment which enables the tests specified in this ETS to be carried out. Equipment Under Test (EUT): For the purpo
36、ses of this ETS the EUT includes all units necessary for intended operation. This includes: - - - the Externally Mounted Equipment (EME); the Internally Mounted Equipment (IME) including the data terminal equipment such as keyboard, Visual Display Unit (VDU), printer, etc.; all interconnecting cable
37、s and power supply leads. - ETSI ETS*300*460 %b 3Y001%55 0105294 913 Page 10 ETS 300 460: May 1996 I 3.2 Abbreviations For the purposes of this ETS, the following abbreviations apply: CMF EGC EIRP EMC EME EUT FARI GMDSS IME IMO MMSS NCF MMSI RF SOLAS STE VDU Control and Monitoring Function Enhanced

Since this test equipment will be specific for the p
40、articular system, it is not possible to provide detailed specifications in this ETS. However, the following baseline is provided: - special test arrangements are required to simulate the satellite signal, thus enabling the ship earth station to transmit, to allow measurement of transmission paramete
41、rs; - any specification of these special test arrangements which may have direct or indirect effects on any specification of this ETS shall be clearly stated by the manufacturer; - the STE shall prevent any radiation of signals, and it shall be certified by the system operator to be suitable for suc
42、h purpose; - when using STE it shall be ensured that no transmission to the satellite occurs. 4.2 Test report The test report shall contain: - the value of the nominated bandwidth declared by the manufacturer; - the results of the test; - all parameters and operational conditions.

Verification: The equipment shall successfully complete the performance checks under the conditions, defined in annex
46、A. 6 General requirements 6.1 Equipment certification Purpose: To ensure that the ship earth station has obtained certification for operating in the satellite system to be used for communications in the GMDSS. Specification : The ship earth station shall have obtained certification for operating in
47、the satellite system to be used for communications in the GMDSS as required by IMO Resolution A.663(16) 7, section 2 or IMO Resolution A.664(16) 8, section 2. Verification: By documentary evidence. 6.2 Power supply 6.2.1 Power supply reversal Purpose: To ensure that the equipment is protected from t
48、he effects of reversal of the power supply polarity. Specification: Means shall be incorporated for the protection of equipment from reversal of the power supply polarity. ETSI ETS*300*460 96 3400855 0305296 796 m I Page 12 ETS 300 460: May 1996 Verif ication: The ship earth station shall be connect
49、ed to a power supply of reversed polarity at nominal voltage. If a protection fuse blows during this test it shall be replaced. Normal power supply polarity shall then be restored and a performance check carried out successfully. 6.2.2 Power supply interruption Purpose: To ensure satisfactory operation after power supply interruption. Specification : Any interruption of the power supply of up to 60 seconds duration shall not require the equipment to be manually re-initialised and shall not result in change or loss of stored operational parameters or in loss of stored messa
