The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The proposed μKF achieves estimation performance nearly identical to that of the classical Kalman filter and its variants, with small and bounded estimation errors. The mean square estimation error (MSEE) remains low for all state variables under both noise configurations.

C2weakest assumption

Satellite dynamics are accurately captured by the chosen linearized radial-angular model and the two measurement noise sources are mutually independent with known covariance matrices.

C3one line summary

Applies and compares micro-Kalman filter with classical KF, EKF, UKF and adaptive KF for linearized satellite state estimation under two noise models.
