FIELD: space technology.
SUBSTANCE: serving satellite for providing position keeping services to the main satellite has a body and a gripping mechanism. The gripping mechanism is configured to be attached to the docking ring to form a connection between the main satellite and the serving satellite. Attaching the gripping mechanism to the docking ring forms a connected unit having a common centre of mass. The serving satellite has at least two motors and at least one controller. Said controller maintains the coupled unit in stationary orbit by selectively orienting two said motors so that thrust vectors of said two motors do not pass through a joint centre of mass, and each of them is offset from a joint centre of mass.
EFFECT: possibility of ensuring extension of service life of the main satellite is achieved.
