Estimation of the required thrust impulse for performing of LSC transition maneuver from the injection to the working orbit, correction of the orbital altitude and LSC submersion maneuver in the target area of the World ocean is presented. Numerical values of thrust impulse estimation for the given inertial-mass parameters of LSC are given.</p>Small weight and size spacecraft (LSC)oxygen-hydrogen propulsion system on the basis of water electrolysislow thrust engine system using gas fuelmaneuver of transition from one orbit to anotherorbit correction maneuverLSC submersion maneuverМаломассогабаритный космический аппараткислородно-водородная установка с электролизом водысистема двигателей малой тяги на газовом топливеманёвр перехода между орбитамиманёвр коррекции орбитыманёвр затопления
