RaspiUSBL: An open-source Raspberry Pi-Based Passive Inverted Ultra-Short Baseline Positioning System for Underwater Robotics
Jin Huang, Yingqiang Wang, Ying Chen
Precise underwater positioning remains a fundamental challenge for underwater robotics because global navigation satellite system (GNSS) signals cannot penetrate the sea surface. T…
Precise Time Delay Measurement and Compensation for Tightly Coupled Underwater SINS/piUSBL Navigation
Jin Huang, Yingqiang Wang, Haoda Li +3
In multisensor systems, time synchronization is particularly challenging for underwater integrated navigation systems (INSs) incorporating acoustic positioning, where time delays c…
Analytical Covariance Propagation for DVL-Aided Loosely Coupled SINS Under Attitude Uncertainty
Jin Huang, Zichen Liu, Haoda Li +5
In loosely coupled strapdown inertial navigation system/Doppler velocity log (SINS/DVL) integration, the body-frame DVL velocity is projected into the navigation frame using the SI…
An Improved ESO-Based Line-of-Sight Guidance Law for Path Following of Underactuated Autonomous Underwater Helicopter With Nonlinear Tracking Differentiator and Anti-saturation Controller
Haoda Li, Zichen Liu, Jin Huang +2
This paper presents an Improved Extended-state-observer based Line-of-Sight (IELOS) guidance law for path following of underactuated Autonomous Underwater helicopter (AUH) utilizin…
