GNSS and LEO clocks

Precision timing solutions for modern networks

As networks adapt to support generative AI, machine-to-machine communication and the growth of autonomous systems, precise synchronization has become more critical than ever. Small cells are set to play a pivotal role in next-generation connectivity, including 6G development and beyond, making accurate timing essential. Our GNSS clock portfolio provides the perfect solution, delivering reliable synchronization even in challenging environments like urban canyons. This comprehensive range of devices supports multiple GNSS constellations, including GPS, GLONASS, BEIDOU and GALILEO, to ensure global compatibility. With assured PNT capabilities, combining diverse sources such as GNSS and Satellite Time and Location (STL) services, Oscilloquartz GNSS clocks empower networks to maintain resilience and precision across all deployment scenarios.


Advanced GNSS clocks for highly reliable timing

Our GNSS clocks feature innovative technologies designed to ensure synchronization excellence. By combining GNSS and STL signals, they provide enhanced resilience against jamming, spoofing and other security threats. Advanced monitoring with real-time synchronization diagnostics ensures potential issues are addressed before they impact services. Compact designs with industry-leading energy efficiency make our devices ideal for deployments in space-constrained or environmentally challenging locations. They also support a wide range of timing protocols, including PTP, NTP and legacy methods like IRIG, making them versatile enough for both modern and traditional synchronization networks.


Scalable timing solutions supporting diverse industries

Oscilloquartz GNSS clocks are built to serve diverse applications across industries. From enabling precise timing for 5G rollouts in telecom to supporting financial trading, smart grids, broadcasting and defense, our solutions are specifically engineered for flexibility. They can be deployed at the network’s core, edge or even in GNSS-denied environments, using STL signals to penetrate indoor locations without rooftop antennas. Designed with modularity and environmental hardening, they provide scalable solutions that grow with evolving network needs, guaranteeing dependable performance in even the most challenging settings.


Future-proof network synchronization systems

Aligned with zero-trust architectures to boost security and reliability, our GNSS clock portfolio is essential for future-ready synchronization solutions. Assured PNT capabilities ensure uninterrupted timing even in the face of GNSS vulnerabilities, protecting critical infrastructure against jamming and spoofing threats. With flexible purchasing options, including time-as-a-service and GNSS-backup-as-a-service models, Oscilloquartz GNSS devices offer both operational simplicity and long-term value. By tackling the complex demands of modern networks and ensuring compatibility with evolving standards, they provide a versatile foundation for synchronization infrastructure. Cost-effective and dependable, our GNSS clocks meet today’s challenges while being fully prepared to address the needs of tomorrow.
