Improving the Performance of Multi-GNSS (Global Navigation Satellite System) Ambiguity Fixing for Airborne Kinematic Positioning over Antarctica [PDF]

, 2019
Conventional relative kinematic positioning is difficult to be applied in the polar region of Earth since there is a very sparse distribution of reference stations, while precise point positioning (PPP), using data of a stand-alone receiver, is ...

Characteristics of Large‐Scale Traveling Ionospheric Disturbances During the 10 May 2024 Geomagnetic Storm

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Based on the total electron content (TEC) observation in the Asian‐Australian and American sectors, this paper investigates the characteristics and hemispheric asymmetry of large‐scale traveling ionospheric disturbances (LSTIDs) during the 10 May 2024 superstorm. We found that the amplitudes and meridional phase velocities of LSTIDs in the two

Characteristics of Stratospheric Gravity Wave Spectra and Their Dynamic Linkage With Convection

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Gravity wave (GW) spectra can visualize the energy distribution between different scales. A large amount of data from the round‐trip intelligent sounding system in southern China is used to investigate the GW vertical spectra and the poorly studied stratospheric horizontal spectra of horizontal winds.

Molecular Epidemiology and Genetic Diversity of Orientia tsutsugamushi From Patients and Small Mammals in Xiangyun County, Yunnan Province, China

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Scrub typhus is caused by Orientia tsutsugamushi (OT). In this study, the detection rates of OT in patients and small mammals were 28.13% (18/64) and 13.98% (13/93), respectively. Nine full‐length 56‐kDa TSA genes were identified, comprising four distinct genotypes: Karp‐like (n = 3), Kato‐like (n = 3), Gilliam (n = 2), and TA763 (n = 1). Recombination

3D Reconstruction of Equatorial Plasma Bubbles Using EOF and GNSS Radio Occultation Data From MSS‐1 and COSMIC‐2

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract This study presents initial scientific insights obtained from Radio Occultation (RO) observations of ionospheric irregularities and scintillation at equatorial and low latitudes collected by the Macau Science Satellite‐1 (MSS‐1). With a specific focus on the South Atlantic Anomaly (SAA) region, an Empirical Orthogonal Function (EOF ...
