摘　　要：在有些特殊应用场合如车载移动测图系统,要求的是高精度的定位定姿结果而不要求实时性,针对这一应用特点,提出了使用DGPS的位置信息来纠正SINS的起始失准角误差,实际应用表明:该方法取得了较好的效果,可满足工程应用的要求。In special area such as vehicle mobile mapping system, post high accuracy of position and attitude is required. Contraposed to these characteristics of the integrated system , a new method which using the position information of DGPS to calibrate misalignment angle of static initial self-alignment is introduced. The practical application results illustrate the efficiency of the new method, which can be accorded with the demand of engineering.
