Which consequence results when a poorly conditioned Kalman filter diverges?

A)State estimate contains unbounded errors
B)Measurement noise is minimized accurately
C)Process noise becomes perfectly predictable
D)System dynamics become strictly linear

💡 Explanation

The state estimate diverges when the **innovation covariance** is underestimated; because an underestimation trusts the process model too much, therefore propagating errors rather than correcting them via new measurements, leading to unbounded errors.
