The use of precession modulation for nutation control in spin-stabilized spacecraft [PDF]
The relations which determine the nutation effects induced in a spinning spacecraft by periodic precession thrust pulses are derived analytically. By utilizing the idea that nutation need only be observed just before each precession thrust pulse, a ...

A determination of the radio-planetary frame tie from comparison of Earth orientation parameters [PDF]
, 1992 The orientation of the reference frame of radio source catalogs relative to that of planetary ephemerides, or 'frame tie,' can be a major systematic error source for interplanetary spacecraft orbit determination.

Nutation and the Oppolzer's Terms [PDF]
Symposium - International Astronomical Union, 1980 Two fundamental frames of reference are used in the study of the rotation of the Earth: the nonrotating celestial coordinate system XYZ attached to the directions to stars and/or extragalactic sources, and the terrestrial coordinate system xyz attached in “a prescribed way” to several points (observatories) on the surface of the Earth or to the pencil ...

A Dual‐Ion Multiphysics Model for Smart and Sustainable Sensors Based on Bacterial Cellulose
Advanced Intelligent Systems, EarlyView.Bacterial cellulose (BC), functionalized with ionic liquids (ILs) and conductive polymers, offers promise for sustainable sensor applications. To enable real‐world integration, this work presents the first dual‐carrier, multiphysics white‐box model of mechanoelectric transduction in BC–IL sensors, combining mechanical deformation and ion transport ...

Precession-Nutations and Tidal Potential [PDF]
International Astronomical Union Colloquium, 1971 We have previously established (Melchior and Georis, 1968) the equations connecting the development of precession-nutation with the tesseral part of the tidal potential. These equations are:whereωiAirespectively represent the frequencies and amplitudes of the tidal waves, ω the Earth’s rotation velocity,
