LOW-ORBIT EARTH SATELLITE Russian patent published in 2001 - IPC

Abstract RU 2167790 C1

FIELD: space engineering; designing and development of artificial satellites injected into orbits at altitude of 200 to 700 km. SUBSTANCE: according to invention, overall dimensions, mass and aerodynamic characteristics of satellite are selected depending on apogee and perigee altitudes of working orbit, as well as on preset satellite existence time. These characteristics ensure ballistic coefficient of satellite whose upper bound is found from special relationship. Relative maximum permissible random deviations due to technological errors, deviations of drag coefficient and mass of satellite are introduced into this relationship. EFFECT: extended operational capabilities of satellite due to avoidance of premature recovery from working orbit because of atmospheric braking. 1 dwg, 2 tbl
