FEATURE OBJECT ATTRIBUTES

Attribute: Category of GMDSS Area

Acronym: CATGMD Code: ?

Camel case: categoryOfGMDSSArea

Attribute type: Simple

Data type: Enumeration

Expected input:

ID Meaning INT 1 M-4

1 : Area A1

2 : Area A2

3 : Area A3

4 : Area A4

Definitions: (all IMO)


Area A1

Within range of VHF coast stations with continuous DSC alerting available (about 20 – 30 miles)


Area A2

Beyond area A1, but within range of MF coastal stations with continuous DSC alerting available (about l00 miles)


Area A3

Beyond the first two areas, but within coverage of geostationary maritime communication satellites (in practice this means Inmarsat). This covers the area between roughly 70 deg N and 70 deg S.


Area A4

The remaining sea areas. The most important of these is the sea around the North Pole (the area around the South Pole is mostly land). Geostationary satellites, which are positioned above the equator, cannot reach this far.
