A correction method of encoder bias in satellite laser ranging system

Geodesy and Geodynamics, 2013
In a satellite laser ranging telescope system, well-aligned encoders of the elevation and azimuth axes are essential for tracking objects. However, it is very difficult and time-consuming to correct the bias between the absolute-position indices of the ...

A comprehensive study of plasmonic mode hybridization in gold nanoparticle‐over‐mirror (NPoM) arrays

Nanophotonics, Volume 14, Issue 27, Page 5347-5361, December 2025.
Abstract Hybrid plasmonic systems that combine localized and propagative surface plasmons offer new opportunities for tunable light–matter interactions at the nanoscale. This paper provides the most comprehensive study to date of hybridization between gap localized surface plasmons (gap LSP) and diffraction‐mediated propagative surface plasmon ...

On a new observable for measuring the Lense-Thirring effect with Satellite Laser Ranging [PDF]

, 2002
In this paper we present a rather extensive error budget for the difference of the perigees of a pair of supplementary SLR satellites aimed to the detection of the Lense-Thirring effect.Comment: LaTex2e, 14 pages, 1 table, no figures.

Time-Variable Gravity Field from the Combination of HLSST and SLR

Remote Sensing, 2021
The Earth’s time-variable gravity field is of great significance to study mass change within the Earth’s system. Since 2002, the NASA-DLR Gravity Recovery and Climate Experiment (GRACE) and its successor GRACE follow-on mission provide observations of ...

Quantifying Past and Future Terrestrial Water Storage Scarcity Across China Through Midcentury

Earth's Future, Volume 13, Issue 10, October 2025.
Abstract Terrestrial water storage (TWS) in China, with the world's largest irrigated expanse and extensive mid‐low latitude glaciers, is essential for effective water resource management and socioeconomic risk adaptation. However, the responses of TWS to human intervention and climate change, both during historical periods and under future scenarios ...

On the reliability of the so far performed tests for measuring the Lense-Thirring effect with the LAGEOS satellites

, 2005
In this paper we will show in detail that the performed attempts aimed at the detection of the general relativistic Lense-Thirring effect in the gravitational field of the Earth with the existing LAGEOS satellites are often presented in an optimistic and

Declining Body Condition of Territorial Male Australian Fur Seals: Correlations With Environmental Variables

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT The Australian fur seal ( Arctocephalus pusillus doriferus , AUFS) population, currently less than 47% of its pre‐harvest size, represents the largest resident marine predator biomass in south‐eastern Australia. This region, characterized by low marine productivity and rapid warming, is home to Kanowna Island, the third‐largest AUFS colony ...

How to reach a few percent level in determining the Lense-Thirring effect?

, 2004
In this paper we discuss and compare a node-only LAGEOS-LAGEOS II combination and a node-only LAGEOS-LAGEOS II-Ajisai-Jason1 combination for the determination of the Lense-Thirring effect. The new combined EIGEN-CG01C Earth gravity model has been adopted.
