Operation of the spacecraft flight involves the following steps:

GLONASS-M satellite

Removal of a satellite into orbit after its separation from the booster, there is checking of all onboard systems; cast and production satellite in the system with the specified point of the period of revolution and the angular position of the system in the plane (the duration of this stage - from one week to one month and is determined by the angular position of the satellite at the point of the launch system and satellite point); staffing of the satellite; satellite location outside the system (for example, for preventive and remedial works on the command from the control center).
