Electromagnetic compatibility and Radio spectrum Matters (ERM) - Technical characteristics and methods of measurement for shipborne watchkeeping receivers for reception of Digital Selective Calling (DSC) in the maritime MF, MF/HF and VHF bands

The present document states the minimum operational and performance requirements for shipborne receivers intended to be connected to an external installation, including a decoder for DSC, and used as receivers for watchkeeping DSC on board ships operating in the mobile MF, MF/HF and VHF band allocated in the ITU Radio Regulations [1] to the maritime mobile service, both in connection with distress and safety communication and in connection with general communication. These requirements include the relevant provisions of the ITU Radio Regulations [1], Recommendation ITU-Rs M.493-13 [3], M.541-9 [9] and the IMO Resolutions A.803 (19) [i.5], A.804 (19) [i.6], A.806 (19) [i.7] and A.694 (17) [i.4]. The present document specifies also technical characteristics, methods of testing and required test results for dedicated watchkeeping receivers for use with radio installations in the GMDSS as required by chapter IV of the SOLAS [i.8]. DSC watchkeeping receivers may be a separate equipment or be integrated with a DSC or radiotelephone equipment. For integrated equipment the present document specifies the requirements and methods of testing of the DSC watchkeeping receivers only. DSC watchkeeping receivers can be either fixed-frequency receivers or, in MF/HF bands, scanning receivers. Requirements for the DSC equipment or radiotelephone equipment are given in EN 300 338-2 [10], EN 301 925 [i.1] and EN 300 373-1 [i.3] respectively.

Elektromagnetna združljivost in zadeve v zvezi z radijskim spektrom (ERM) - Tehnične karakteristike in merilne metode za ladijske stražne sprejemnike za sprejem digitalnega selektivnega klica (DSC) v pomorskih pasovih MF, MF/HF in VHF

Ta dokument navaja minimalne zahteve glede delovanja in zmogljivosti za ladijske sprejemnike, ki so namenjeni povezavi z zunanjo napravo, vključno z odkodirnikom za digitalne selektivne klice (DSC), in se uporabljajo kot sprejemniki za ladijske stražne DSC, ki delujejo v mobilnih pasovih MF, MF/HF in VHF, dodeljenih pomorskim mobilnim storitvam v okviru pravilnika ITU o radiokomunikacijah [1], in sicer v zvezi z zasilno in varnostno komunikacijo ter splošno komunikacijo. Te zahteve vključujejo ustrezne določbe pravilnika ITU o radiokomunikacijah [1], priporočil ITU-R M.493-13 [3], M.541-9 [9] ter resolucij Mednarodne pomorske organizacije (IMO) A.803 (19) [i.5], A.804 (19) [i.6], A.806 (19) [i.7] in A.694 (17) [i.4]. Ta dokument navaja tudi tehnične karakteristike, preskusne metode in zahtevane preskusne rezultate za ustrezne stražne sprejemnike za uporabo z radijskimi napravami v globalnem pomorskem zasilnem in varnostnem sistemu (GMDSS), kot je zahtevano v 4. delu Mednarodne konvencije o varstvu človeškega življenja na morju [i.8]. Stražni sprejemniki za sprejem digitalnega selektivnega klica (DSC) so lahko ločena oprema ali so vgrajeni v opremo za DSC ali radiotelefonsko opremo. Ta dokument za vgrajeno opremo določa zahteve in metode za preskušanje izključno stražnih sprejemnikov za sprejem DSC. Stražni sprejemniki za sprejem DSC so lahko sprejemniki s stalno frekvenco ali sprejemniki, ki skenirajo pasove MF/HF. Zahteve za opremo za sprejem DSC ali radiotelefonsko opremo so podane v standardih EN 300 338-2 [10], EN 301 925 [i.1] in EN 300 373-1 [i.3].
