How does CSOSS handle sensor data validation?

• A. CSOSS sequences require verification of data integrity, stability, and appropriate source before acting on it.
• B. Sensor data is accepted without validation if it comes from a sensor.
• C. Validation is optional and occurs after mission.
• D. Data validation requires backup manual data only.

Answer: (A)

Sensor data validation in CSOSS is built into how sequences decide what to do. Before acting on any sensor input, the system checks that the data is intact (data integrity), stable over a short period (stability), and comes from the expected source (appropriate source). If all checks pass, the sequence continues and uses that data to drive the response. If any check fails, the action is not taken and the system may hold, trigger a safe-state, or switch to a different data source, preventing responses to corrupted, unstable, or spoofed information. Accepting data without validation would risk unsafe actions; making validation optional or after the mission would be unreliable; relying on manual backup data only would ignore automatic validation and timeliness.
