An Asynchronous Two-Speed Kalman Filter for Real-Time UUV Cooperative Navigation Under Acoustic Delays
A two-speed Kalman filter with history projection maintains real-time UUV navigation accuracy under up to 30-second acoustic delays by decoupling fast dead-reckoning from slow collaborative updates.
