  • Использование частот в морской подвижной службе
    Существуют дуплексная и симплексная связь.
    Дуплексная связь представляет собой способ связи, при котором передача возможна одновременно в обоих направлениях канала радиосвязи.
    При симплексной связи передача возможна попеременно в каждом из двух направлений связи. Симплексная связь, как правило, осуществляется на одной частоте, в то время как дуплексная связь требует применения двух частот.
    Полудуплексная связь — это способ симплексной связи на одном конце радиолинии и дуплексной связи на другом. Полудуплексная связь требует применения двух частот.
    Частота передачи береговой станции, спаренная с частотой передачи судовой станции, называется парной частотой. Каждой береговой станции присваивается одна или несколько пар частот, каждая пара имеет частоту для приема и частоту для передачи, которые образуют канал связи.
    Частоты, выделенные и используемые для вызова, называются вызывными частотами. Остальные частоты являются рабочими частотами. Конкретные правила и процедуры по организации, планированию и эксплуатации связи в морской подвижной службе содержатся в Регламенте радиосвязи (РР), издаваемом Международным союзом электросвязи (МСЭ).
    Правила, касающиеся использования частот в МПС, изложены в статье 60 PP. В данной статье указаны полосы частот, предназначенные для использования береговыми и судовыми станциями в конкретных режимах излучения, а также даны ссылки на Приложения к РР, содержащие таблицы частот передачи и каналов в соответствующих полосах частот МПС.

    156,650 М Гц (канал 13) Для связи между судами, относящейся к безопасности навигации.
    156,8 МГц (канал 16) Для радиотелефонного обмена в случае бедствия и для обеспечения безопасности.
    Полоса 406-406,1 МГц Используется исключительно спутниковыми радиомаяками — указателями места бедствия в направлении Земля — космос
    Диапазон 1,5 ГГц Используется в морской подвижной спутниковой службе в направлении космос-Земля.
    Диапазон 1,6 ГГц Используется в морской подвижной спутниковой службе в направлении Земля-космос.
    Полоса 9200-9500 МГц Используется радиолокационными транспондерами для облегчения поиска и спасания.
