Helicopter Test of a Strapdown Airborne Gravimetry System [PDF]
Sensors, 2018 Airborne gravimetry from a helicopter has been a feasible tool since the 1990s, with gravimeters mounted on a gyro-stabilised platform. In contrast to fixed-wing aircrafts, the helicopter allows for a higher spatial resolution, since it can move slower ...

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

SGA-WZ: A New Strapdown Airborne Gravimeter [PDF]
Sensors, 2012 Inertial navigation systems and gravimeters are now routinely used to map the regional gravitational quantities from an aircraft with mGal accuracy and a spatial resolution of a few kilometers. However, airborne gravimeter of this kind is limited by the inaccuracy of the inertial sensor performance, the integrated navigation technique and the kinematic

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.
