Part B - Satellite Signal

  1 The satellite EPIRB should include facilities to transmit in the 1,644.3 to 1,644.5 MHz frequency band and, after full implementation of the second generation Inmarsat space segment, in the frequency band 1,645.5 to 1,646.5 MHz only. Alternatively, the satellite EPIRB distress alert could be transmitted sequentially in the 1,644.3 to 1,644.5 MHz frequency band and the frequency band 1,645.5 to 1,646.5 MHz. After full implementation of the second generation Inmarsat space segment, the emission should be limited to the frequency band 1,645.5 to 1,646.5 MHz only.

  2 The technical characteristics of the transmitted signal and the message format should be in accordance with Recommendation ITU-R M.632.footnote The binary system codes on the satellite radiopath and its decimal representations are used for in-system control, commissioning and registration. The system code is fixed into the Inmarsat-E EPIRB and protected through its entire life against any unauthorized change.

  3 The system code should be made part of all messages. The Inmarsat-E registration database, which is maintained by Inmarsat, matches the applicant identity and any alphanumeric form of national identity to the unique system code.
