Optimal fusion‐based localization method for tracking of smartphone user in tall complex buildings

CAAI Transactions on Intelligence Technology, Volume 8, Issue 4, Page 1104-1123, December 2023., 2023
Abstract In the event of a fire breaking out or in other complicated situations, a mobile computing solution combining the Internet of Things and wearable devices can actually assist tracking solutions for rescuing and evacuating people in multistory structures. Thus, it is crucial to increase the positioning technology's accuracy. The sequential Monte

Adaptive weighted federated Kalman filtering based on Mahalanobis distance and its application in navigation

IET Communications, Volume 17, Issue 17, Page 1962-1973, October 2023., 2023
This paper proposes the adaptive weighted federated Kalman filtering based on Mahalanobis distance (MD‐AWFKF). Firstly, by calculating the Mahalanobis distance between the predicted value and the measured value of the system state, the random fluctuation of the measured value is detected.

Antarctic Sedimentary Basins and Their Influence on Ice‐Sheet Dynamics

Reviews of Geophysics, Volume 61, Issue 3, September 2023., 2023
Abstract Knowledge of Antarctica's sedimentary basins builds our understanding of the coupled evolution of tectonics, ice, ocean, and climate. Sedimentary basins have properties distinct from basement‐dominated regions that impact ice‐sheet dynamics, potentially influencing future ice‐sheet change.

Cook Ice Shelf and Ninnis Glacier Tongue Bathymetry From Inversion of Operation Ice Bridge Airborne Gravity Data

Geophysical Research Letters, Volume 50, Issue 11, 16 June 2023., 2023
Abstract The seafloor depths under the Cook Ice Shelf and Ninnis Glacier Tongue have not been directly measured, despite their importance for understanding ocean circulation and ice shelf change. We model the bathymetry underneath the floating ice and surrounding ocean using airborne gravity data.

Airborne Absolute Gravimetry With a Quantum Sensor, Comparison With Classical Technologies

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 4, April 2023., 2023
Abstract We report an airborne gravity survey with an absolute gravimeter based on atom interferometry and two relative gravimeters: a classical LaCoste&Romberg (L&R) and a novel iMAR strapdown Inertial Measurement Unit. We estimated measurement errors for the quantum gravimeter ranging from 0.6 to 1.3 mGal depending on the flight conditions and the ...

Multisensor Data Fusion for Robust Pose Estimation of a Six-Legged Walking Robot [PDF]

, 2011
For autonomous navigation tasks it is important that the robot always has a good estimate of its current pose with respect to its starting position and - in terms of orientation - with respect to the gravity vector.

Novel pedestrian navigation system based on zero velocity update procedure technology and improved Sage‐Husa adaptive Kalman filter with index fading memory factor

IET Wireless Sensor Systems, Volume 13, Issue 2, Page 48-57, April 2023., 2023
To obtain a high‐precision pedestrian location result under the environments that there is no GNSS signal, the paper proposes a novel pedestrian navigation system by using the zero velocity update procedure technology (ZUPT) and the improved Sage–Husa Adaptive Kalman Filter (SHAKF) based on index fading memory.
