The article examines the fundamental components of parameters of the Earth's rotation used to produce high accuracy navigation systems for spacecraft. An appropriate model to describe the fundamental components of the pole oscillations and irregularity in axial rotation of the Earth is constructed considering the orbital motion and the gravitational tidal effects of the Sun and the Moon. Knowledge of these parameters aboard the SC is necessary to solve problems of SC navigation support. The accuracy of the proposed models is analyzed with respect to the periodicity of their corrections using actual values transmitted from the MCC to the SC. It is shown that the proposed models ensure sufficient self regulation of the Earth's rotation parameters generated aboard the SC. Source

The classical mechanical problem on the motion on a system of two or several bodies is stated in terms of parameters of the 13-parameter extended Galilean group (translations, rotations, boosts, and gravitational transformations) without using such traditional notions as "point" and "force." © 2012 Allerton Press, Inc.

Analysis of errors in atmospheric density measurements by lidar on board the ISS is performed. It is shown that using as the lidar transmitter a Nd:YAG laser with moderate parameters of emission at a wavelength of 353 nm and a receiving mirror diameter of 0.4 m, it is possible to cover with a 10% measurement error a height range, on average, from 40–60 km and 30–40 km in the nighttime and daytime, respectively, down to the troposphere. Working with emission at 266 nm with a 10% error, it is possible to move to the heights of the mesosphere (70 km) and penetrate the atmosphere down to a height of 40 km. Thus, the use of two harmonics makes it possible to assimilate the height range of atmospheric density measurements from on board the ISS beginning from 70 km and down to the troposphere. © 2016, Pleiades Publishing, Ltd.

The aim of the present paper is to give a survey of those exact solutions of relativistic inertial navigation equations which are directly or indirectly related to Thomas precession. Various cases of uniform circular motion of an object in gravity-free space close to motion with inertial or orbital attitude are considered. © 2014 Allerton Press, Inc. Source
