Multi-GNSS Disciplining
It doesn’t just rely on one satellite network—it continuously verifies signals across GPS, Galileo, BeiDou, and GLONASS to ensure a stable and resilient holdover.
Triple-Clock Validation
It’s not enough to take time from one source. The Open Time Appliance runs a real-time clock quorum algorithm, cross-checking multiple references to eliminate bad data and prevent drift.
Designed for all network
The Open Time Appliance supports Precision Time Protocol (PTPv2) and Synchronous Ethernet (SyncE) —ensuring that time is distributed with extreme accuracy.
Real-time Drift & Spoof Detection
If a time source starts to drift, the Open Time Appliance detects the anomaly and rejects bad data before it ever affects your network.
If a GPS signal is spoofed, it flags and corrects the error—keeping your system secure and accurate.

Clock Quorum Technology
The power of 3, because precision needs proof.
The Open Time Appliance, has built in clock quorum technology, not only for resilience but to evidence the synchronisation capabilities.
Too many devices on the market claim precision with little in the way of testing capabilities, our systems provide raw evidence with clear metrics and comparisons through a concenses mesh.
Low on Space & Power
With all 3 units only taking up 1RU of 19" rack space. You no longer need to sacrifice expensive datacentre space and power resources for gold standard timing.All of our units fit the same form factor, which means even a rubidium device is capable of being deployed in even the most space constrained environments.
Resilience and Redundancy
Tripple modular redundancy provides the most robust and resilient system. This is not only fault tolerant but also enhnaces synchronisation capabiities.The Open time appliance is a low cost solution to tripple modular redundancy as purchasing 3 units is typically less than 2 units from our competitors.
<5ns Accuracy and Precision
Flagship solutions integreated into all of our models from Ublox allow these devices to be accurate to less than 5 nanoseconds to UTC.
With advanced features for anti-jam and anti-spoof counter measures these units maintain accuracy and precision even during sub-optimal conditions
Frequency Generation
From OCXO to high-end atomic rubidium and low-swap caesium
It must use a single-board computer that is deployed in millions of units for the best reliability
It must run the same Timebeat software that works so well everywhere already.
