Получены соответствующие погрешности абсолютных значений углов нутации для различных значений динамического сжатия ядра Земли. Результаты оценки использованы при построении новой модели нутации и проведении анализа бюджета неопределенностей этой модели.</p></abstract><trans-abstract xml:lang="en"><p>The estimation of error caused by the use of transfer function for biaxial Earth at calculation of nutation angles is carried out on nanosecond level of accuracy. The corresponding errors of absolute values of nutation angles for various values of dynamic compression of Earth’s core are received. The results have been used at new nutation model construction and at carrying out of the analysis of the budget of this model uncertainties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вращение Земли</kwd><kwd>глобальная геодинамика</kwd><kwd>нутация</kwd><kwd>Earth rotation</kwd><kwd>global geodynamics</kwd><kwd>nutation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mathews P.
