45、MISSION _ MARITIME NAVIGATION AND RADIOCOMMUNICATION EQUIPMENT AND SYSTEMS AUTOMATIC IDENTIFICATION SYSTEM (AIS) Part 1: AIS Base Stations Minimum operational and performance requirements, methods of testing and required test results FOREWORD 1) The International Electrotechnical Commission (IEC) is

46、 a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to

47、other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in t

48、he subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with condit

49、ions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for in
