A spacecraft with a spacecraft body having a first axis of symmetry, X, a second axis of symmetry, Y, and a third axis of symmetry, Z. The spacecraft has four thrusters. A control system is provided on the spacecraft which is in electrical contact with the first, second, third and fourth thrusters and which controls the activation and deactivation of the first, second, third and fourth thrusters so that the attitude and orbital velocity of the spacecraft can be controlled only by the first, second, third and fourth thrusters.

[ I claim:] [1.] A three axis body stabilized spacecraft comprising:a spacecraft body having a first axis of symmetry, X, a second axis of symmetry, Y, and a third axis of symmetry, Z;a first thruster aligned along a first line parallel to said Z-axis;a second thruster aligned along a first line par
[ I claim:] [1.] A three axis body stabilized spacecraft comprising:a spacecraft body having a first axis of symmetry, X, a second axis of symmetry, Y, and a third axis of symmetry, Z;a first thruster aligned along a first line parallel to said Z-axis;a second thruster aligned along a first line parallel to said X-axis;a third thruster aligned along a second line parallel to said Z-axis;a fourth thruster aligned along a second line parallel to said X-axis,wherein said first, second, third, and fourth aligned thrusters provide thrust and positive and negative torque about each of said X, Y and Z axes, andwherein said first, second, third and fourth thrusters are located only at an aft end of said spacecraft body; anda control system in electrical contact with said first, second, third and fourth thrusters, wherein said control system controls the activation and deactivation of said first, second, third and fourth thrusters so that the attitude and orbital velocity of said spacecraft can be controlled by the torque and thrust of only said first, second, third and fourth thrusters wherein said first line parallel to said Z-axis and said first line parallel to said X-axis intersect one another at a first point of intersection.
