The Position and Orientation System (POS) is a strapdown inertial navigation system (SINS)/GPS integrated measurement equipment, which can provide position, attitude and others movement information of a rigid body. It has been a key technology to improve the image resolution such as SAR, InSAR, Imaging spectroscope, LiDAR, Camera. To decrease mechanically dithered effect of RLG and improve aseismatic capability of POS, the kinetics model of ISA was established based on the vibration responding mechanism. An optimized design rule of RLG POS was proposed to reduce the measurement error. Moreover, the size effect and the compensation method of RLG POS were analyzed. Based on the finite element analysis software, a high precision RLG POS was design and developed successfully.
Dr. Jianli Li (1979) obtained his PhD degree from School of Instrument Science and Opto-electronic Engineering in Beijing University of Aeronautics and Astronautics (BUAA) in 2008. He is a Lecturer of BUAA, and mainly researching the SINS/GPS integrated system. He was the Principle Investigator of several projects supported by the National Natural Science Foundation, National 973 Sub Program of China. In addition, he has participated in a few projects supported by National High-tech Research and Development Program of China. His research team had developed a series of the high-precision Position and Orientation System (POS) applied in airborne SAR motion compensation.
