What is meant by sensor redundancy and why is it important in MW operations?

• A. Having a single, primary sensor reduces complexity.
• B. Relying on external data sources is sufficient without onboard sensors.
• C. Having multiple sensors provide overlapping data to ensure continuity if one sensor fails.
• D. Sensor redundancy means replacing sensors annually.

Answer: (C)

Sensor redundancy means using multiple sensors that provide overlapping data so you don’t rely on a single source. In MW operations this matters because sea environments are harsh and equipment can fail or be degraded. If one sensor goes offline or starts giving faulty readings, the other sensors keep supplying information, preserving awareness, navigation, and targeting capability. It also allows cross-checking data to catch anomalies and supports sensor fusion for more reliable estimates. For example, using radar alongside electro‑optic/IR sensors, and pairing GPS with inertial navigation, helps maintain accurate position and tracking even if one sensor is at risk. Redundancy enables graceful degradation, reduces single points of failure, and strengthens mission resilience and safety.
