IMO Resolutions

The

International Maritime Organization The International Maritime Organization (IMO; ; ) is a List of specialized agencies of the United Nations, specialized agency of the United Nations responsible for regulating maritime transport. The IMO was established following agreement at a ...

(IMO) has made several resolutions on performance standards of shipborne GNSS receivers, corresponding to the IEC standards for different GNSS constellations and receiver equipment. On 1 December 2000, the

(IMO) adopted three resolutions regarding the performance standards for shipborne GNSS receivers: * IMO RESOLUTION MSC.112(73), corresponding to the IEC 61108-1 test standard * IMO RESOLUTION MSC.113(73), corresponding to the IEC 61108-2 test standard * IMO RESOLUTION MSC.114(73), corresponding to the IEC 61108-4 test standard On 5 December 2006, a fourth resolution was adopted: * IMO RESOLUTION MSC.233(82), corresponding to the IEC 61108-3 standard Further resolutions include IMO Resolution A.1046(27).
