The invention discloses a thruster layout method for a truss type GEO (geostationary orbit) satellite adopting subdivision optimization design. Basic demands of truss type GEO satellite thrusters for subdivision modular design in thrusting service module layout are met, and layout azimuth angles of four 10N thrusters mounted at four corners of a thrusting service module back plate are designed according to demands of highest possible satellite orbital maneuver efficiency, enough capability of overcoming disturbance torque of a high-thrust orbit maneuver engine, combination of sedimentation of propellants and three-axis attitude control, angular momentum unloading and the like; under the adverse condition that the centroid of the whole satellite is remarkably higher than the upper end of a thrusting service module, a thrust vector slant and parallel layout method for 10N thrusters in pairs is adopted for layout of thrusters for east-west station keeping and south-north station keeping, so that layout of the thrusters for east-west station keeping combines functions of pitch attitude control and angular momentum unloading, layout of the thrusters for south-north station keeping combines functions of rolling, pitching, off-course attitude control and angular momentum unloading, and propellants for attitude control and angular momentum unloading are saved.
