Open Time Appliance Mini
Precision Time. Zero Complexity.
The simplest way to deploy ultra-accurate PTP & NTP — in a form factor that fits anywhere.
Modern systems don't fail because of compute.
They fail because of time drift.
Microseconds matter.
And complexity kills deployment.
So we built something different.
Timing. Simplified.
Plug & Play Deployment
Cable in, system live. No complex setup wizards, no rack-mount gymnastics. Connect power, connect network, deploy timing.
Enterprise Accuracy
5ns accuracy to UTC with multiband GNSS. The same precision expected from full-sized grandmasters, in a compact device.
No Overhead
No dedicated NIC, no separate management plane, no complex licensing. All PTP profiles, NTP, PPS and frequency distribution.
GNSS Powered
Multi-constellation L1/L2/L5

Built for Every Industry
Every system depends on time.
5G & Telecom
Phase-accurate timing for 4G/5G RAN synchronisation, transport networks, and fronthaul infrastructure.
Finance
MiFID II compliant timestamping for trading systems, order books, and financial data centres.
Broadcast & Media
SMPTE ST 2059-2 and AES67 profile support for studios, OB workflows, and live production.
Defence
Resilient timing for radar, tracking systems, and tactical networks with OSNMA anti-spoofing.
Power & Utilities
IEEE C37.238 Power Profile support for substation automation, PMUs, and smart grid timing.
Autonomous Systems
Precise sensor fusion timing for autonomous vehicles, robotics, and industrial IoT platforms.
Every system depends on time.
Not just accurate. Proven accurate.
Multi-source GNSS, continuous monitoring, and built-in validation give you confidence that your timing is trustworthy — not just precise.
Multi-Source GNSS
GPS, Galileo, GLONASS, and BeiDou across L1/L2/L5 bands. Multiple constellations mean fewer single points of failure.
Monitoring & Validation
Continuous signal quality monitoring with Galileo OSNMA authentication on the PT model. Know your timing source is genuine.
Real-World Resilience
DOCXO holdover rides through 24 hours without GNSS. Optional battery keeps the whole system alive through power loss.
Engineered to Fit Anywhere
Smaller than traditional grandmasters.
Powerful enough to replace them.
Rack it, desk-mount it, or carry it into the field. The OTA Mini's compact aluminium enclosure fits where full-size grandmasters can't — edge cabinets, outside broadcast vans, temporary deployments, and constrained telecom sites.
