Title: Method of control of moment of momentum of spacecraft in the course of orbital correction and system for realization of this method
Inventor: KOVTUN V S
IPC: B64G1/28

Granted: 2002-01-27
Abstract: FIELD: attitude control systems; control of orbit of center of mass of spacecraft. SUBSTANCE: proposed method includes determination of required rate of correction of spacecraft orbit and maintenance of preset attitude by means of powered gyroscopes in the course of correction. Position of total moment of momentum of spacecraft relative to magnitudes in powered gyroscope system (S) is determined. Preset area (S r ) where total moment of momentum of spacecraft shall lie at the moment of completion of orbital correction is predicted. In case of saturation of gyroscopes, change of indicated moment of momentum of spacecraft till the moment of completion of their unloading is predicted. Prediction is made taking into account disconnection of pair of attitude-control motors for unloading. All operating attitude-control motors are taken into account from the end of unloading till completion of correction. Position of predicted total moment of momentum of spacecraft relative to preset area S r  and its present magnitude in area S of magnitude are checked simultaneously. If both these conditions are not fulfilled, orbit correction is continued at simultaneous unloading of gyroscope system. In case even one of conditions is fulfilled, unloading is discontinued. Provision is made for control system containing all units required for performing all operations of proposed method. EFFECT: reduced number of starts of attitude-control motors for unloading powdered gyroscopes; reduced consumption of propulsive mass and reduced effect on spacecraft orbit. 3 cl, 9 dwg

Abstract: FIELD: industrial inorganic synthesis. 
     SUBSTANCE: invention relates to developing electrochemical method for preparation of high-purity germanium hydride appropriate for use as germanium source in microelectronics. Germanium hydride is prepared by electrolysis of water-alkali solution containing germanium dioxide in concentration from at least 40 g/l to solubility limit, said electrolysis being effected on nickel cathode in diaphragm electrolyzer at current density 1.0-1.5 A/cm 2  and temperature no higher than 65 о С. In particular, electric current is passed through water-alkali solution over a period of time required for achieving minimum allowable limit of impurities. Electrolysis is effected by cross-mixing of electrolyte streams, wherein electrolyte stream from cathode space is supplied into anode space after separation of germanium hydride and hydrogen and electrolyte streams from anode space into cathode space after separating oxygen. Synthesized germanium hydride is then isolated from its mixture with hydrogen. Isolated germanium hydride is further purified using membrane technique to achieve summary level of impurities (SiH 4 , AsH 3 , PH 3 , H 2 S, CH 4 , Fe, Ni, Al, Ca, Mg, etc.) does not exceed 1·10 -6  to 1·10 -7 %, which is acceptable for rather wide application areas. Use of membrane technique offers an way for freeing germanium hydride of suspended particles 0.05 mcm in size to level below 5.5·10 -3  particles/mole, which makes product acceptable for such areas as optics and laser engineering. Productivity of method is 40-50 g/h. 
     EFFECT: enhanced germanium hydride purification efficiency.
