Impacts of Arc Length and ECOM Solar Radiation Pressure Models on BDS-3 Orbit Prediction
Remote Sensing, 2022 The BeiDou global navigation satellite system (BDS-3) has already provided worldwide navigation and positioning services for which the high-precision BDS-3-predicting orbit is the foundation.

Evaluation of strategies for the ultra-rapid orbit prediction of BDS GEO satellites
Geo-spatial Information Science, 2023 The quality of BeiDou Navigation Satellite System (BDS) Geostationary Earth Orbit (GEO) ultra-rapid products is unsatisfactory because GEO satellites are nearly stationary relative to ground stations.

Detection of the Orbital Hall Effect by the Orbital-Spin Conversion [PDF]
Memorial Volume for Shoucheng Zhang (World Scientific, 2021,
Chapter 13), 2020 The intrinsic orbital Hall effect (OHE), the orbital counterpart of the spin Hall effect, was predicted and studied theoretically for more than one decade, yet to be observed in experiments. Here we propose a strategy to convert the orbital current in OHE to the spin current via the spin-orbit coupling from the contact.

Orbit Predictions for Space Object Tracked by Ground-Based Optical and SLR Stations
Remote Sensing, 2022 In many cases, we have few optical observations over a short time span, and most of the information generated is too limited to compute a full orbit according to the angles-only method.

Effect of lunar gravity models on Chang'E-2 orbit determination using VLBI tracking data
Geodesy and Geodynamics, 2016 The precise orbit determination of Chang'E-2 is the most important issue for successful mission and scientific applications, while the lunar gravity field model with big uncertainties has large effect on Chang'E-2 orbit determination.

Magneto-Optical Detection of the Orbital Hall Effect in Chromium [PDF]
Phys. Rev. Lett. 131, 156702 (2023), 2023 The orbital Hall effect has been theoretically predicted but its direct observation is a challenge. Here, we report the magneto-optical detection of current-induced orbital accumulation at the surface of a light 3$d$ transition metal, Cr. The orbital polarization is in-plane, transverse to the current direction, and scales linearly with current density,

Intrinsic Spin Hall Edges [PDF]
, 2005 The prediction of intrinsic spin Hall currents by Murakami \textit{et al.} and Sinova \textit{et al.} raised many questions about methods of detection and the effect of disorder.
