Global Navigation Satellite System (GNSS)

What is THE GNSS?

A Global Navigation Satellite System (GNSS) is a satellite navigation system with global coverage. A group of satellites send signals from space, transmitting the position and timing data to GNSS receivers on earth in order to determine the location of marine vessels. The United States' Global Positioning System (GPS) and Russia's GLONASS GNSS systems have been fully operational since October 2018, with China's BeiDou Navigation Satellite System (BDS) and the European Union's Galileo systems scheduled to be fully operational by 2020.

Why is GNSS testing Important?

While the Marine Equipment Directive (MED) approvals process is primarily for entry into the European market, certification requires that the product is compliant with relevant International Maritime Organization resolutions. MED certificates are therefore widely accepted worldwide. Additionally, as GNSS is a radiodetermination product it falls under the scope of the Radio Equipment Directive (RED). GNSS equipment without the appropriate certification is not in compliance with International Maritime Organization requirements and cannot therefore be legally released onto the market.

The following regulations apply to GNSS systems:

• IEC 61108-x – a test standard series under the MED which specifies the minimum performance standards, methods of testing and required test results for GNSS shipborne receiver equipment, based on the relevant IMO Resolution
• ETSI EN 303 413 – a test standard under the RED which specifies technical characteristics and methods of measurements for GNSS
