Oscilloquartz, a privately owned company headquartered in Switzerland, founded in 1949, operates as an ADVA Optical Networking company and employs approximately 80 individuals. Its main product focus is telecoms. The company offers solutions for time and frequency synchronisation, designing, manufacturing, and deploying end-to-end synchronisation systems over next-generation packet and legacy networks.
On August 19, 2026, Oscilloquartz expanded its US aerospace defense and government presence through agreements with six specialized sales representative firms: ProTEQ Solutions, Southern Marketing Associates (SMA), Testech, TMS Sales, Contech Marketing Associates, and Ward/Davis Associates. This move addresses a rising demand for resilient Position, Navigation, and Timing (PNT) solutions across these sectors as GNSS cyber threats increase, aiming to strengthen market access and customer engagement. Previously, on July 30, 2026, Oscilloquartz won a contract with a quantum computing firm to provide optical cesium solutions, using its OSA 3300 SHP and ESTU precision timing module to deliver the highly stable frequency references needed for coherence and system synchronization in quantum computing. Earlier, on July 29, 2026, Oscilloquartz integrated Galileo’s Open Service Navigation Message Authentication (OSNMA) into its timing and synchronization platforms with u-blox GNSS technology, enhancing secure GNSS timing for critical infrastructure by introducing a new level of trust and resilience to GNSS-based synchronization.
