Galileo Reference Time (GRT)

Galileo Reference Time (GRT) is a precise time standard used by the Galileo satellite navigation system. It provides a consistent and accurate time reference across all Galileo satellites, essential for accurate positioning. GRT is synchronized with Coordinated Universal Time (UTC) but is specifically tailored for Galileo's operations. This synchronization ensures that signals from the satellites can be precisely timed, allowing receivers on the ground to determine their location accurately. In essence, GRT serves as the stable time backbone for the Galileo system, enabling reliable and precise navigation worldwide.
