摘 要:Ship deformation is the main error source of partial reference. Such deformationcan be estimated by laser gyro units and Kalman filter technology. ForKalman filter, deformationwas divide into two parts, dynamic deformation, and static ***, dynamic deformationistreated as AR2 *** this paper,dynamic deformationistaken as a kind of ARX *** on actual data measured by Yuanwang-3 Space Survey Ship, simulation experiments are studied. Results show that the novel model can improve the measurement precision.
