Six-impulse maneuvers for rendezvous of spacecraft in near-circular noncoplanar orbitsSpringer Science and Business Media LLC - Tập 50 - Trang 441-448 - 2012
A. A. Baranov, D. S. Roldugin
The problem of a rendezvous of two spacecraft in close near-circular noncoplanar
orbits is considered. The angles of applying velocity impulses and their
orientation are determined from necessary conditions of optimality derived using
the basis vector theory. For non-degenerate six-impulse solutions the analytical
formulas are found that approximate the dependence of moments of applying
velocity i... hiện toàn bộ
Controlling spacecraft by means of solar radiationSpringer Science and Business Media LLC - Tập 52 - Trang 244-249 - 2014
E. N. Chumachenko, R. R. Nazirov, D. U. Dunhem, A. N. Fedorenko
The possibility of using solar sails in Earth orbit is investigated. The
characteristic parameters of a solar sail consisting of six spheres attached by
mutually orthogonal long rods are estimated.
Families of Periodic Solutions to the Beletsky EquationSpringer Science and Business Media LLC - - 2002
A. D. Bruno
A review of achievements in the investigation of the planar periodic
oscillations and rotations of a satellite around its center of mass, which moves
along an elliptic orbit in the central gravitational field, is presented. These
oscillations and rotations of the satellite are described by an ordinary
differential equation (Beletsky equation) of the second order with periodic
coefficients and two ... hiện toàn bộ
Space System for Detecting Hazardous Celestial Bodies Approaching Earth from the Daytime Sky (SODA)Springer Science and Business Media LLC - Tập 56 - Trang 283-292 - 2018
A. S. Shugarov, B. M. Shustov, S. A. Naroenkov, M. A. Zvereva
The concept of the System for the Observation of Daytime Asteroids (SODA system)
has been developed, the purpose of which is to detect at least 95% of hazardous
celestial bodies larger than 10 m in size that fly towards Earth from the Sun
side. Spacecraft, equipped with the optimum version, which has three wide-angle
optical telescopes of small aperture (20–30 cm) will be placed in a halo orbit

Magneto-ionospheric effects of active experiments conducted on February 18, 2004Springer Science and Business Media LLC - Tập 49 - Trang 292-307 - 2011
L. F. Chernogor
Results of radiophysical and magnetometric observations of dynamical processes
in the ionosphere and geomagnetic field that followed launches of four rockets
of different power and made from different launching sites are analyzed. It is
found that the rocket launches were accompanied by an intensification of wave
activity in the ionosphere and geomagnetic field. The medium reactions from
various s... hiện toàn bộ
A Technique for Estimating the Space Debris Density from the Data of Onboard Recording SystemsSpringer Science and Business Media LLC - Tập 41 - Trang 204-208 - 2003
V. V. Mironov
A three-dimensional mathematical model and a program complex for modeling the
external effect of small-sized space debris particles on a spacecraft are
developed. On the basis of the rectangular contributions method a new technique
is developed for restoring the density of small-sized space debris from a small
number of recorded debris collisions with recording sensors. From the form of
the densit... hiện toàn bộ
Control of a spacecraft’s spatial turn with minimum value of the path functionalSpringer Science and Business Media LLC - Tập 45 - Trang 234-247 - 2007
M. V. Levskii
The problem of optimal (with minimum value of the path functional) control over
a spatial reorientation of a spacecraft is considered. Using the quaternion
method, an analytical solution to this problem is obtained. For the symmetrical
optimality index, the complete solution to the problem of spacecraft
reorientation is represented in a closed form. The results of mathematical
modeling of the spac... hiện toàn bộ
Forecasting of the Total Electron Content at a Single LocationSpringer Science and Business Media LLC - Tập 41 - Trang 353-356 - 2003
I. Stanisławska, Z. Zbyszynski
The autocovariance prediction method previously used for the forecast of VI
derived ionospheric characteristics has been used for forecast of one of the
most important ionospheric—the total electron content (TEC)—at single locations.
Quiet and disturbed conditions at different European stations were studied in
regard to clarify the forecasting capabilities of the method for determination
of the TE... hiện toàn bộ
