New calibration method boosts AUV navigation accuracy without GNSS

By PulseAugur Editorial · [1 sources] ·

Researchers have developed an Information-Aided Calibration (IAC) method to improve the accuracy of Doppler velocity log (DVL) measurements for autonomous underwater vehicles (AUVs). This new approach enhances conventional Kalman filter-based calibration in environments with GNSS signals, achieving up to a 20% improvement. Crucially, IAC also enables GNSS-free DVL self-calibration, which is vital for operations in signal-denied areas, showing up to a 35% improvement in velocity vector estimation. AI

IMPACT Enhances AUV navigation accuracy and reliability, particularly in GNSS-denied environments, enabling more robust autonomous operations.
