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.

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.

Processing algorithm for a strapdown gyrocompass
Scientia Iranica, 2012 AbstractThe problem of gyrocompassing using inertial sensors, i.e., gyros and accelerometers, is addressed. North finding, with an order of accuracy of one arc-min, is not only required for the initial alignment of inertial navigation systems, but also has a critical role to play in the guidance and navigation of ships that navigate for long periods of

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 ...
