The only technology to provide a relative frequency stability better than 1x10-15 for integration times ranging from 1 s to 104 s (about 6x10-15 on the day). Uliss does not require the boring and especially expensive use of liquid helium. As demonstrated by the implementation of our first prototype in the new Deep Space Network Station of ESA, in Malargüe (Argentina), our technology is able to answering the most demanding applications.

Uliss is now able to deliver a low power version of the CSO (see datasheet).

February, 2015

Uliss moved to the SYRTE laboratory (SYstèmes de Référence Temps Espace, Observatoire de Paris, Paris, France) for a two-month measurement campaign.

The ULISS project has been officially launched the 1st of March 2011. Two well skilled young scientists have been hired by the UFC- Business Unit. The project is founded by FEDER, Conseil Régional de Franche-Comté and OSEO
