| 摘 要： | The error coefficient estimation of inertial platform in the course of its consecutive ground calibration is studiedA separate-bias algorithm is adopted to estimate the error parameters effectively. The ill-conditioning problem of the equation solution caused by the huge state dimension is also resolved. And the simulation result shows its validity.
