Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.Abstract The Antarctic Peninsula is a unique sector of the circum‐Pacific continental margin arc where subduction ceased due to a series of ridge‐trench collisions, preserving a relatively un‐deformed magmatic arc. This region, therefore, has the potential to provide key insights into how subduction systems behave during their final stages.

Geometric Approach to Strapdown Magnetometer Calibration in Sensor Frame [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2008 In this work a new algorithm is derived for the onboard calibration of three-axis strapdown magnetometers. The proposed calibration method is written in the sensor frame, and compensates for the combined effect of all linear time-invariant distortions, namely soft iron, hard iron, sensor nonorthogonality, and bias, among others.

IMU and GNSS Postprocessing for High-Resolution Strapdown Airborne Gravimetry
Engineering Proceedings, 2023 Strapdown airborne gravimeters based on a navigation-grade inertial measurement unit (IMU) are highly sensitive to perturbations during aircraft flight, especially in the case of flights in draped mode (at a constant altitude above the terrain) or drone ...

Optimal Look-Angle Guidance with Field-of-View and Impact Angle Constraints for Strapdown Munition
International Journal of Aerospace Engineering, 2022 A strapdown seeker with limited field-of-view (FOV) can simplify and decrease cost of the guidance system for a munition. However, the inherent defect of the strapdown seeker is that it could not provide the necessary line-of-sight (LOS) angular ...

A Combined Navigation Fault Detection Method Based on Wavelet‐ResNet
Electronics Letters, Volume 61, Issue 1, January/December 2025.A combined navigation dataset, using wavelet transform is constructed and a residual network structure is trained for fault detection. The results show that this method can effectively improve the training efficiency and the accuracy of slowly varying faults.

A Student's T Distribution‐Based Filter Design for SINS/GNSS With Heavy‐Tailed Noise
IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.To reduce the affection of outliers caused by heavy‐tailed noise, the noise model is constructed by the Student's T distribution rather than the Gaussian distribution, and the related probability density functions (PDF) are adaptively modelled as student's T PDFs with different DoF parameters.
