TIME DIFFERENCE OF ARRIVAL

UWB TDoA Positioning.

One broadcast. Multiple synchronized observations.

Uplink TDoA targets real-time systems with multiple tags. Stations record the arrival of a tag signal and use timing differences to constrain its position. Synchronization, geometry and capacity planning are central to the design.

HOW IT WORKS

From radio signals to usable location.

The same signal reaches different stations at different times. After synchronization or clock-offset correction, time differences become range differences. Multiple hyperbolic or hyperboloid constraints determine position.

SYSTEM ARCHITECTURECONCEPT · NOT LIVE DATA

Tag broadcast

Send scheduled UWB frames and control channel utilization.

Multi-station reception

Capture the same frame and record its timestamps.

Time-difference solution

Correct clocks and solve from arrival-time differences.

Track output

Filter invalid observations and publish usable coordinates.

Fewer tag exchanges

Uplink broadcasts reduce per-station two-way interactions for multi-tag systems.

Central processing

Manage synchronization, observation quality and tracks through a common engine.

Extendable coverage

Plan overlapping station coverage and suitable geometric placement.

DEPLOYMENT ESSENTIALS

Check the deployment requirements.

01Time synchronization is essential. Confirm its implementation and the timing error budget.

02Station count depends on 2D/3D requirements, observability and redundancy; one fixed count cannot suit every deployment.

03The supplied specifications do not provide a TDoA support list. Related UWB products are evaluation candidates only; verify timestamp and firmware capabilities first.
