Study on modeling of inertial instrument in composed overloading-vibrating environment

For modeling the error of inertial instrument in composed overloading and vibrating environment, a modeling approach that combines analytical method with experimental method is adopted. A test plan is designed, and the flowchart of model identification is given. With this approach, a more integrated error model can be built for the inertial instrument, which is important for improving the accuracy of inertial guidance.
