IEC 61108
IEC 61108 is a collection of IEC standards for "Maritime navigation and radiocommunication equipment and systems - Global navigation satellite systems ".
The 61108 standards are developed in Working Group 4 of Technical Committee 80 of the IEC.
Sections of IEC 61108
Standard IEC 61108 is divided into seven parts, each relating to a different GNSS system's receiver equipment, performance requirements, methods of testing, and required test results:- IEC 61108-1: Global positioning system equipment
- IEC 61108-2: Global navigation satellite system equipment
- IEC 61108-3: Galileo equipment
- IEC 61108-4: Shipborne DGPS and DGLONASS maritime radio beacons
- IEC 61108-5: BeiDou equipment
- IEC 61108-6: Indian Regional Navigation Satellite System equipment
- IEC 61108-7: Satellite-Based Augmentation System equipment
IMO Resolutions
The International Maritime Organization 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 International Maritime Organization adopted three resolutions regarding the performance standards for shipborne GNSS receivers:
- IMO RESOLUTION MSC.112, corresponding to the IEC 61108-1 test standard
- IMO RESOLUTION MSC.113, corresponding to the IEC 61108-2 test standard
- IMO RESOLUTION MSC.114, corresponding to the IEC 61108-4 test standard
- IMO RESOLUTION MSC.233, corresponding to the IEC 61108-3 standard
