|
|
|
|
| Step | Consumer Action | Measurement |
|
|
|------|----------------|-------------|
|
|
| 1 | Camera-replay sends frame with known timestamp | Record t_capture |
|
|
| 2 | Monitor GPS_INPUT messages at mavlink-inspector | Record t_gps_input for first GPS_INPUT update after t_capture |
|
|
| 3 | Compute latency = t_gps_input - t_capture | Per-frame latency |

**Steps**:
|
|
|
|
| Step | Consumer Action | Measurement |
|
|

### NFT-PERF-04: Satellite Matching Latency (Async)
|
|
|
|
**Summary**: Validate satellite matching completes within 330ms per keyframe (async, does not block VO).
|
|
**Traces to**: AC-07 (within frame budget), solution processing time budget
