Method of retaining geostationary spacecraft in preset orbital position

FIELD: transport. SUBSTANCE: invention relates to space engineering and is intended for retaining in preset geostationary orbital position. After spacecraft gravity center control term extended, no ground means of navigation parameters measurement are used to compute the schedule of spacecraft gravity center motion displacement by one correction engine to fix, at every correction step, the start and finish of free displacement of inertial mass aboard spacecraft inside spherical closed vessel. Magneto susceptible ball makes said inertial mass. Control acceleration is defined from equation of uniformly accelerated motion without initial velocity in known path in said vessel by means of high-precision accelerometer of linear accelerating effect in no-gravity effects. Correction engine operation duration is defined to define correction engine switch-off time. EFFECT: higher accuracy, lower power consumption, longer life. 1 dwg, 2 tbl
