The Galileo Reference Centra (GRC) is located in Noordwijk, the Netherlands. It is a cornerstone of the Galileo service provision. From Initial Services to full operational capability and beyond, it provides the European GNSS Agency (GSA) with an independent system to evaluate the quality of the signals in space. In doing so, it helps the GSA ensure the delivery of high-quality navigation services so users can better rely on and benefit from Galileo. The European GNSS Agency is responsible for the management of the GRC, including its development and operations.
