Verification boundary: This page combines platform design guidance with static evidence from the release. It does not prove that every detected interface is enabled, reachable, secure, or operational in the deployed environment.
Timing and positioning role
OpenPNT should register and monitor the clocks, coordinate frames and position sources used by sensors, radios, tracks, simulations and analytic products. Accurate correlation requires knowing not only a timestamp and coordinate, but also their source, reference frame, uncertainty and quality.
Required metadata
| Area | Minimum context |
|---|---|
| Time | UTC timestamp, clock source, synchronization method, offset/error estimate and leap/time-scale handling. |
| Position | Coordinate reference system, datum, origin, axes, units, uncertainty and update time. |
| Sensor geometry | Platform pose, antenna/camera offsets, orientation and calibration profile. |
| Simulation | Scenario clock, time acceleration, federation epoch and mapping to wall-clock time. |

Verification tests
- Confirm NTP/PTP/White Rabbit service state and measured offset on every participating host.
- Verify sensor products carry source timestamp and clock-quality metadata end to end.
- Validate coordinate transforms against known control points and record calibration versions.
- Alert when time or position quality falls below mission thresholds instead of silently accepting degraded data.
