Long-period nutational-precessional motions of the instantaneous Earth rotation pole

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2020
The influence of the rotational regime on real long-period nutational-precessional motions of the instantaneous pole of the Earth’s rotation is considered. The solar magnetospheric (through changes in the angular velocity of rotation) mechanism of action

Earth pressure calculation for bucket wall of offshore bucket foundation

open access: yesShuili Shuiyun Gongcheng Xuebao, 2018
The calculation of the earth pressure under the action of wind and wave loads is the key to analyze the stability of the offshore bucket foundation structure.When the bucket foundation structure rotates, the displacement model is more complicated than ...

Formation Design for Single-Pass GEO InSAR Considering Earth Rotation Based on Coordinate Rotational Transformation

open access: yesRemote Sensing, 2020
The single-pass geosynchronous synthetic aperture radar interferometry (GEO InSAR) adopts the formation of a slave satellite accompanying the master satellite, which can reduce the temporal decorrelation caused by atmospheric disturbance and observation ...

Improved IMU Preintegration with Gravity Change and Earth Rotation for Optimization-Based GNSS/VINS

open access: yesRemote Sensing, 2020
IMU preintegration technology has been widely used in the optimization-based sensor fusion framework, in order to avoid reintegrating the high-frequency IMU measurements at each iteration and maintain the ability of bias correction when bias estimation ...

Contribution of CRUST2.0 components to the tri-axiality of the Earth and equatorial flattening of the core

open access: yesGeodesy and Geodynamics, 2013
Equatorial flattening of the core were previously estimated to be 5 × 10−4 by using seismically derived density anomaly, and 1.7748280 × 10−5 by assuming that the ratio of polar flattening to equatorial flattening of the core is the same as that of the ...

Rotation-Rotation Mechanism moving with Respect to a Plane [PDF]

open access: yesINCAS Bulletin, 2019
The relative motion of a robotic arm formed by homogeneous bars of different lengths and masses, hinged to each other is investigated. The first bar of the mechanism is articulated on a platform, considered for three cases: placed on the surface of the ...

Prograde and Retrograde Terms of Gravimetric Polar Motion Excitation Estimates from the GRACE Monthly Gravity Field Models

open access: yesRemote Sensing, 2020
From 2002 to 2017, the Gravity Recovery and Climate Experiment (GRACE) mission’s twin satellites measured variations in the mass redistribution of Earth’s superficial fluids, which disturb polar motion (PM).

Interaction between variable solar UV radiation and tropospheric circulations as a possible cause of five year oscillation in Earth rotation [PDF]

open access: yesSerbian Astronomical Journal, 2000
It is shown that Five Year Oscillation in Earth rotation is possibly caused by variable solar UV radiation and a corresponding perturbation mechanism is suggested.

OSCILLATIONS OF DRY AIR IN THE ATMOSPHERE

open access: yesНаука. Инновации. Технологии, 2022
Introduction. The article examines the influence of the terrain and the daily rotation of the Earth on the oscillatory processes in the atmosphere. It is shown that as a result of the superposition of two oscillatory processes, caused both by natural ...
