Abstract
A satellite, intended to be placed in a station in orbit about a celestial body, including a first electrical thruster of orientatable thrust direction, a second electrical thruster of orientatable thrust direction, and an electrical thruster of fixed orientation that is fixed with respect to the satellite and of line of thrust passing through the center of gravity of the satellite. The satellite includes two electrical-thruster power units and an electrically interconnecting network connecting a first power unit to the first thruster of orientatable thrust direction and to the thruster of fixed orientation, and connecting a second power unit to the second thruster of orientatable thrust direction and to the thruster of fixed orientation. Each of the power units is configured to power either the associated thruster of orientatable thrust direction or the thruster of fixed orientation.
