Sector use case
A short walkthrough of how TimeBeat hardware is deployed across this sector — the architecture, the operational realities and the customer outcomes.
How TimeBeat hardware delivers anti-jam, anti-spoof timing for tactical and fixed-site defence networks.
Why
Modern defence networks can no longer assume GNSS. Adversaries jam it, spoof it, and in theatre you may lose it for hours. When GPS lies, everything downstream from radar to targeting to comms lies with it. Defence operators need timing infrastructure that can be audited line-by-line, that survives sustained GNSS denial, and that doesn't depend on proprietary black boxes from foreign vendors.
GPS jamming and spoofing are now routine threats. Without anti-jam and anti-spoof protection at the receiver, adversaries can silently degrade your entire timing chain — long before an operator notices anything wrong.
A mission can't pause while the clock drifts. You need holdover that keeps you within operational tolerance for hours or days, not minutes — and you need to know exactly how accurate you still are.
Black-box timing from foreign vendors is a supply-chain and trust liability. Defence buyers need open designs, open firmware and an audit trail from silicon to software.
From fixed-site command centres to vehicle-mounted tactical units, timing has to be ruggedised, power-efficient, and deployable without a rack engineer on every site.

Deployments
01
Open Time Appliance with Rubidium Black+ as the grandmaster, feeding PTP to the command network. Clock Ensemble fuses multiple sources for resilience.
02
Open TimeCard Mini V3 mounted in rugged command vehicles. Shock-rated, multi-band GNSS, integrated OCXO for on-the-move operations.
03
Open Time Appliance Mini with battery pack — validate deployed timing in the field without pulling gear apart.
04
PTP² Mesh for self-healing topology + Clock Ensemble for multi-source fusion. Survive GNSS denial without a single point of failure.
