Space Propulsion Mission Design and Attitude Control Task Mission design Orbit changes Plane changes Orbit trim Stationkeeping Repositioning Attitude Control Thrust vector control Attitude control Attitude changes Reaction wheel unloading Maneuvering (Translational velocity change) Convert one orbit to another Change orbital plane, other orbit parameters remaining constant Remove Iaunch vehicle errors Maintain constellation position Change constellation position (RotationaI velocity change) Remove vector errors Maintain an attitude Change attitudes Description Remove stored momentum Repositioning the spacecraft axes
Space Propulsion coplanar orbit changes changing a circular orbit to a coplanar elliptical orbit generalised coplanar maneuvre ΔV 2 = V 2 i + V 2 f − 2V V i f cosα ΔV is smallest when this term is largest cosα = 1 the transfer can be made at any intersection of two orbits. the least velocity change is necessary when the orbits are tangent and α is zero
