The LISA Technology Package on board of LISA PATHFINDER will enable testing of following LISA key technologies: 'Inertial Sensor': to demonstrate that the test masses are really flying free of all external influences and to detect changes in the position and orientation of the satellite relative to the proof mass; 'disturbance-free flight control': multiple sets of thrusters at µ-Newton levels (not part of LTP) will be used to control the spacecraft position to a few microns. The thrusters are to counteract the changes in position and orientation of the spacecraft due to external forces in order to keep it centred on the proof mass. This will also include test of the algorithms of the system control. laser interferometer': to measure the absolute position and attitude and the difference in the displacement of the two proof masses to validate that each is 'disturbance-free' within the requirements.
