Test mass pose measurement using laser displacement sensor

This report focuses on a measurement of mass, position and orientation which is implemented with a new version of inertial sensor in the space microgravity environment. Six laser displacement sensors are applied in the detection system. According to the principle of Six-point-location, the three orthogonal faces of the mass cube are solved correspondingly; the pose condition is derived after the compute. According to the derived overall solution algorithm, the simulation is performed by computer to verify its validity and accuracy. During this process, the influence of the installation position of the laser displacement sensor on the solution results is found and the corresponding conclusions are given. Meanwhile, two different installation forms of the laser displacement sensor on the same side and the opposite side are given. The advantages of each method are analyzed and the source of error and its influence are also analyzed. Finally, the effective precision is retrieved from the expression and the simulation.
