MSC.1-Circ.1382 - Questionnaire On Shore-Based Facilities For The Global Maritime Distress And Safety System (Gmdss) (Secretariat)

MSC.1/Circ.1382 3 December 2010

QUESTIONNAIRE ON SHORE-BASED FACILITIES FOR THE GLOBAL MARITIME DISTRESS AND SAFETY SYSTEM (GMDSS)
1 The Maritime Safety Committee, at its eighty-eighth session (24 November to 3 December 2010), approved circulation of the attached revised questionnaire on shore-based facilities in the GMDSS prepared by the Sub-Committee on Radiocommunications and Search and Rescue, at its fourteenth session.
2 The revised questionnaire contains the revision of MSC/Circ.684, taking into account changes in the provision of several services as well as the evolution of the database over the years.
3 Member Governments, including those which have submitted answers to MSC/Circ.684, are invited to provide or update, in accordance with the annexed questionnaire, the required information electronically, as far as possible, for inclusion in the GMDSS Master Plan (GMDSS.1 circular).
4 Administrations should submit information obtained, as appropriate, from national authorities responsible for shore-based facilities for the GMDSS, NAV/MET Area Coordinators and search and rescue authorities.
5 This questionnaire supersedes MSC/Circ.684.

Criteria for establishing GMDSS sea areas
2.3 Determination of radius A
2.3.1 The following formula should be used to calculate the range A in nautical miles: H is the height of the coast station VHF receiving antenna and h is the height of the ship's transmitting antenna which is assumed to be 4 m.
2.3.2 The following table gives the range in nautical miles (NM) for typical values of H:
2.3.3 The formula given above applies to line-of-sight cases but is not considered adequate for cases where both antennae are at a low level. The VHF range in Sea Area A1 should be verified by field strength measurements.

Criteria for use when providing a NAVTEX service
The ground-wave coverage may be determined for each coast station by reference to Recommendations ITU-R P.368-9 and P.372-10 for the performance of a system under the following conditions:
Frequency - 518 kHz Bandwidth - 500 Hz Propagation - ground wave Time of day & Season - (Administration should determine time periods in accordance with NAVTEX time transmission table (NAVTEX Manual, figure 3) and seasons appropriate to their geographic area based on prevailing noise level.) Transmitter power & Antenna efficiency
- (The range of a NAVTEX transmitter depends on the transmitter power and local propagation conditions. The actual range achieved should be adjusted to the minimum required for adequate reception in the NAVTEX area served, taking into account the needs of ships approaching from other areas. Experience has indicated that the required range of 250 to 400 nautical miles can generally be attained by transmitter power in the range between 100 and 1,000 W during daylight with a 60% reduction at night.) - RF S/N in 500 Hz bandwidth - 8 dB (Bit error rate 1 x 10-2) - Percentage of time - 90
Full coverage of NAVTEX service area should be verified by field strength measurements.
