Space vehiclesSatellitesMeteorologyOrbitsSatellite broadcastingDatabasesMagnetosphereA large database of anomalies, registered by 220 satellites in different orbits over the period 1971-1994, has been compiled. For the first time, data of 49 Russian Kosmos satellites have been included in a statistical ...
A series of statistical analyses made it possible to quantify, for different satellite orbits, space weather conditions in the days characterized by anomaly occurrences. In particular, very intense fluxes (>1000 particles cmssr(pfu) at energy >10 MeV) of solar protons are linked to anomalies ...

revealed that the classical atomic decompositions of such spaces can be obtained as consequences of the action of the group on these spaces. just like the classical besov space \(\dot{\textrm{b}}^{0}_{1,1} (\mathbb {r}^d)\) is (in a certain sense) the minimal banach space being ...
greatly mitigating the effects of model error.This method has been also been validated for space objects with perigee altitude higher than 600 km.The relative errors of estimated BC values from the new method are significantly smaller than those from the direct estimation methods used in numerical ...
Space debris larger than 1 cm can damage space instruments and impact Earth. The low-Earth orbits (at heights smaller than 2000 km) and orbits near the geostationary- Earth orbit (at 35786 km height) are especially endangered, because most satellites orbit at these latitudes. With current ...
Also, adding more stations in a regional network shows almost no improvements on the satellite orbits if the number of stations is more than 16. With the help of ISL observations, however, the satellite orbits determined with a small regional network can reach the same accuracy as that with ...
Method and a system for putting a space vehicle into orbit, using thrusters of high specific impulse The method serves to place a space vehicle, such as a satellite, on a target orbit such as the orbit adapted to normal operation of the space vehicle and starting from an elliptical initial...

aAs time evolves, a point representing a system state in the phase space describes a trajectory (or orbit). The knowledge of this orbit implies the solution of the equations of motion. Stable orbits (attractors) mean stable system behaviours. This apparent continuity in the possible evolution of...
