All-European Maser in Safran’s facilities

In early 2025, Safran Timing Technologies released the first version of an All-European Maser as part of an effort coordinated by the European Space Agency (ESA). This first step helps to address immediate customer needs while paving the way for the final, fully state-of-the art European ground active hydrogen maser.

The technology was tested in a pre-operational environment at ESOC’s Ground Segment Reference Facilities to ensure compatibility with user requirements.

In August 2025, ESA deployed the All-European-Maser at one of its deep-space ground stations, located in New Norcia, Australia. This critical phase will put the clock in operational conditions and demonstrate its reliability supporting all ESA deep-space missions.

As part of this, it will support two 35-meter-diameter deep space antennas: the existing NNO-1 antenna and the upcoming NNO-3 antenna, which will be inaugurated on 4 October 2025.
