If a discrepancy arises between a sensor track and a corroborating sensor, how should it be handled?

• A. Investigate the discrepancy, recheck data sources, and may suspend engagement until resolved.
• B. Proceed with engagement as planned; discrepancies are ignored.
• C. Only rely on the corroborating sensor and dismiss the other.
• D. Replace hardware immediately without analysis.

Answer: (D)

When sensors disagree, the priority is to verify data integrity and keep decision-making reliable. Don’t act on a single measurement; instead, recheck data sources and timing, confirm sensor health and calibration, and run cross-checks with any available corroborating information or fusion outputs. If the discrepancy persists, pause or adjust engagement as appropriate to avoid misinterpretation while you diagnose the cause. Use the fusion system’s confidence weighting to assess which source is more trustworthy under current conditions, and consider environmental factors, sensor faults, or interference as potential reasons for disagreement. Document findings and follow established fault-isolation procedures. Hardware replacement should come after careful analysis and identification of a likely fault, not as an immediate reflex.
