For completeness we consider motions of Galilean and Einsteinian both subluminal and superluminal particles. The presented approach can easily be generalized to more general models of spacetime.</abstract><trans-abstract xml:lang="ru">Показывается, что можно описывать движения релятивистски-ковариантным образом без использования собственного времени. Для полноты мы рассматриваем галилеево-инвариантные и релятивистски-инвариантные движения как досветовых, так и сверхсветовых частиц. Предложенный подход может быть легко распространен и на более общие модели пространства-времени.</trans-abstract><kwd-group xml:lang="en"><kwd>proper time</kwd><kwd>coordinate time</kwd><kwd>Minkowsky space-time</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>собственное время</kwd><kwd>координатное время</kwd><kwd>пространство-время Минковского</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ugarov V.
