ABSTRACT OF THE DISCLOSURE The invention relates generally to a method of regulating the onboard voltage of a spacecraft and of steering the same by at least two contrarotating motor-generator dynamo-electrical machines. According to the method, there are provided two phases: - the energy storage mode, during which each machine receives electrical energy from solar generators through a velocity controll- ing generator commanded from a synthesis of the data relating to position and rotor velocity; and - the energy restitution mode, during which each generator supplies energy to a load consisting of the onboard equipment of the satellite. Output monitoring systems effect a synthesis of the data relating to position rotor velocity and additionally control the power switches. According to the same method, there is also provided on board of said spacecraft, electronic equipment which is divided into two main sections: - electronic control equipment; and - electronic processing equipment, itself divided into two parts: control means positioning system and a computing system.
