1. Reason for revision
The revision is designed to revise some parts of the Technical Standards for Maritime Radio Equipment for such purposes as their alignment with the international standards (ITU/IMO) for the safety of human life and maritime vessels, as well as deregulation, by deleting unnecessary provisions:
2. Main contents
a. (Location information transmitting device for search and rescue purposes) It aims to relax the regulatory requirements of the technical standards for search and rescue, which previously were tightened compared to the international standards, and to have them represented in diagram form at the level of the international standards (Article 8).
b. (Satellite Emergency Radio Positioning System) It adds the relevant contents as the international standards have been revised, making it mandatory for ships to be equipped with a satellite emergency positioning system with the function of automatic ship identification (Article 11).
c. (Shipboard Communication Station) It clearly defines the occupied frequency bandwidth for the channel spacing of shipboard communication stations, as the previously inadequate definition has caused difficulties in testing, etc. *(Article 14-2).
* Analog transmitting devices using a channel spacing of 25 kHz have an occupied frequency of 16 kHz, while analog transmitting devices using a channel spacing of 12.5 kHz have an occupied frequency of 8.5 ㎑, etc.
d. (Autonomous maritime radio appliances) It provides for alignment with the international standards by following the ITU recommendations in order to resolve ambiguities in transmitted messages, such as identification codes and navigation status (Article 26).
e. (Ultra-shortwave frequency for maritime mobile services) It corrects some commentary errors (Same as current → Channel 70 should be used exclusively for digital selective calling, etc.) (Appendix 1).
