FIELD: space vehicles used for operation in geostationary and high-elliptical orbits when protracted stabilization relative to earth is required together with high level of power requirements. SUBSTANCE: space vehicle has cylindrical instrument container, swivel solar-battery panels whose axis of rotation is coaxial relative to longitudinal axis of instrument container and heat-insulating shield made in form of cylindrical sleeve mounted coaxially relative to instrument container; container is placed inside this cylindrical sleeve. One end of container is connected with bottom of sleeve; side wall of container is additionally connected with side surface of sleeve by means of rolling-contact bearings; cylindrical radiator-cooler is mounted on other end of container coaxially relative to it through thermal insulator. Side wall of shield has opening with baffle plates located over its longitudinal edges; they are used for shielding the radiator-cooler from rear side of solar-battery panels. EFFECT: enhanced efficiency. 2 cl, 3 dwg
