Oscilloquartz, a privately owned company headquartered in Switzerland, was founded in 1949, employs approximately 80 individuals, and reported $25.5M in revenue as of 2023. The company specializes in providing solutions for time and frequency synchronisation, designing, manufacturing, and deploying end-to-end synchronisation systems over next-generation packet and legacy networks.
On April 22, 2026, Oscilloquartz detailed how assured synchronization can be maintained in contested defense and aerospace environments, where GNSS disruption is an operational reality and satellite-based timing alone is insufficient for secure communications and coordinated avionics. Previously, on February 24, 2026, Oscilloquartz partnered with Tupaia to showcase high-precision GNSS positioning for mobile operators and enterprises, leveraging existing timing infrastructure with Oscilloquartz grandmasters to support Tupaia's cloud-positioning service for new applications like IoT. In late 2025, Oscilloquartz introduced its OSA 5410XG and OSA 5401XG SyncPlug™ solutions on December 29, focusing on distributed synchronization, delivery validation, and monitoring of time, with the OSA 5410XG designed as a carrier-class Grandmaster for access and aggregation layers. This followed a December 14, 2025 announcement that AEROTHAI implemented Adtran’s compact multi-source Oscilloquartz timing platforms, supplied by NEC, to boost GNSS resilience for national air traffic control, aiming to modernize its network with precise, resilient synchronization and protection against GNSS disruptions to improve safety and efficiency.
