Integrated precise orbit determination for LEO constellation and BDS-3 MEO satellites using inter-satellite links and onboard BDS-3 observations

Satellite Navigation
By leveraging the high-precision spatial reference established with Global Navigation Satellite System (GNSS), we propose a low-ground-dependency and low-latency Precise Orbit Determination (POD) method employing onboard GNSS, Inter-Satellite Link (ISL ...

Assimilation of Earth Rotation Parameters to determine ocean mass change

, 2008
Earth rotation parameters (ERP) are measuredwith very high accuracy. Changes in the ERP originate in movements ofmass within the Earth system. Therefore, these changes can be used todistinguish the eustatic from the steric effects in sea levelchange.

Rationally Designed Bilayer Passivation Strategy for High‐Performance Vacuum‐Processed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
A bilayer “Anchor‐and‐Seal” passivation strategy using EDAI2 and 4MeO‐PEAI effectively mitigates surface defects in vacuum‐processed perovskite films through synergistic hydrogen bonding and Lewis base coordination. This approach optimizes interfacial energy alignment and suppresses non‐radiative recombination, enabling vacuum‐deposited p‐i‐n ...

Chandler wobble excitation by catastrophic flooding of the Black Sea

Annals of Geophysics, 1999
It is now widely accepted that during the late Quaternary glaciation the Black Sea formed an isolated inland lake (Ross et al., 1970). New geological data and the recognition of sudden population movements away from the Black Sea coasts suggest that the ...

Uncertainty determination of Earth Rotation Parameters from LLR by parameter variation during data analysis

, 2022
Lunar Laser Ranging (LLR) has been measuring the distance between the Earth and the Moon since 1969. The IfE LLR dataset includes more than 30,000 normal points (NPs), currently until the end of April 2022.

Coating Artificial Spider Silk Fiber with Magnetic FeCo: An Effective Strategy for Creating a Flexible Magneto‐Responsive Material

Advanced Functional Materials, EarlyView.
An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...

Photometrical observations and shape modeling of space debris in medium Earth orbits

Solar-Terrestrial Physics
The circular medium Earth orbits with a period of about half a day in the inclination range from 50° to 70° are used by various global navigation satellite systems (GNSS), such as GLONASS, GPS, Beidou, Galileo.

Influence of coronal mass ejections on parameters of high-speed solar wind: a case study

Journal of Space Weather and Space Climate, 2018
We investigate the case of disagreement between predicted and observed in-situ parameters of the recurrent high-speed solar wind streams (HSSs) existing for Carrington rotation (CR) 2118 (December 2011) in comparison with CRs 2117 and 2119.

Texoskeletons: Developing the Fundamental Technologies for Creating Intelligent Soft Robotic Clothing With Integrated 1D Sensors and Actuators

Advanced Functional Materials, EarlyView.
ABSTRACT Traditional wearable exoskeletons rely on rigid structures, which limit comfort, flexibility, and everyday usability. This work introduces the fundamental technologies to create the first soft, lightweight, intelligent textile‐based exoskeletons (Texoskeletons) built using 1D sensors and actuators.
