Abstract
A satellite designed to be spin-stabilized in geostationary orbit which has, coaxial with a spin rotation axis, a satellite body surrounded with a cylindrical solar generator, an apogee maneuver system disposed along the axis and two axially disposed equipments. The apogee maneuver system has opposite one of the equipments at least two thrusters oriented parallel to the axis but offset relative thereto by the same distance. Equi-angularly spaced around the other of the two equipments, the thrusters are connected to a common liquid propellant feed system.

A satellite adapted to be spin-stabelized in geostationary orbit comprising:
- a satellite body having a spin rotation axis;
- a cylindrical solar generator disposed circumferentially around said satellite body;
- at least two equipments axially and oppositely disposed on said satellite body;
- and
- an apogee maneuvering system disposed along said spin rotation axis, said apogee maneuvering system being secured to said satellite body opposite one of said at least two equipments, said apogee maneuvering system comprising at least two thrusters oriented parallel to said spin rotation axis, each one of said at least two thrusters being offset from said spin rotation axis by an equal desitance, said at least two thrusters being equi-angularly spaced with respect to an other of said at least two equipments, said at least two thrusters further being connected to a common liquid propellant feed system.
