2011 the NEW-500KHZ-NETWORK is in progress

[OLIVIER F6DGU]

1 ITU-R Study Group 5, at its last meeting on 22 and 23 November 2010,
approved
Report ITU-R M.2201 (11/2010) – Utilization of the 495-505 kHz band by
the maritime
mobile service for the digital broadcasting of safety and security
related information from
shore-to-ships. It was decided that this Report should be brought to
the attention of IMO
(the NAV and COMSAR Sub-Committees, and the International NAVTEX
Coordinating Panel),
IEC, IALA, WMO, IHO and CIRM.
2 This Report describes a technical approach allowing the reuse of the
500 kHz band
for digital broadcasting of maritime safety and security related
information for the benefit of
ships at sea. Systems based on this technical approach can coexist
with the worldwide
NAVTEX system that operates on 490 kHz, 518 kHz, and in some cases 424
kHz.
