Aimed at ballistic missile,a strapdown inertial navigation system/celestial navigation system/radar altimeter( SINS/CNS/RA) integrated method was proposed. Since the velocity and position errors' divergent problem of SINS can not be fundamentally solved by conventional SINS/star tracker integrated method,altitude intercept between calculated sea level elevation and observed sea level elevation which was measured by RA is introduced and total differential equation can be deduced. The four-dimensional observa...
