To solve the problem of GPS unstable measurement in ballistic missile's integrated SINS/GPS guidance, considering factors such as fast variation drift, slow variation drift, digital platform angle error, etc, the error model of SINS on ballistic missile was built. A new novel innovation-based adaptive filter was designed to solve GPS unstable measurement. With the error model of measurement, AKF and SKF were applied to realize data fusion. The simulation results show that AKF has higher estimation accuracy and stronger robustness while the GPS has variable noise intensity.
