IEC 61108

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.

Sections of IEC 61108
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

History
On 1 December 2000, the International Maritime Organization - IMO adopted three resolutions regarding the characteristics of shipped GNSS receivers.
