IEC 61108 is a collection of IEC standards for "Maritime navigation and radiocommunication equipment and systems - Global navigation satellite systems (GNSS)".
The 61108 standards are developed in Working Group 4 (WG 4A) of Technical Committee 80 (TC80) of the IEC.
Standard IEC 61108 is divided into four parts:
Part 1: Global positioning system (GPS) - Receiver equipment - Performance standards, methods of testing and required test results
Part 2: Global navigation satellite system (GLONASS) - Receiver equipment - Performance standards, methods of testing and required test results
Part 3: Galileo receiver equipment - Performance requirements, methods of testing and required test results
Part 4: Part 4: Shipborne DGPS and DGLONASS maritime radio beacon receiver equipment - Performance requirements, methods of testing and required test results
On 1 December 2000, the International Maritime Organization - IMO adopted three resolutions regarding the characteristics of shipped GNSS receivers.
On 1 December 2000, the International Maritime Organization - IMO adopted three resolutions regarding the performance standards for shipborn GNSS receivers:
IMO RESOLUTION MSC.112(73) GLOBAL POSITIONING SYSTEM (GPS) RECEIVER EQUIPMENT
IMO RESOLUTION MSC.113(73) GLONASS RECEIVER EQUIPMENT
IMO RESOLUTION MSC.114(73) DGPS AND DGLONASS MARITIME RADIO BEACON RECEIVER EQUIPMENT
IMO RESOLUTION MSC.233(82) GALILEO RECEIVER EQUIPMENT (adopted on 5 December 2006)
