摘　　要：对磁罗经自差校正的经典方法——爱利法在实际操作中的困难和问题进行了分析,结合现代卫星定位技术,提出了一种能够对爱利法校正磁罗经自差进行改进的方法,并对其准确性进行了评估。这种改进不仅延续了传统爱利法校正磁罗经自差的精度,同时也简化了操作流程、降低了难度,并且消除了爱利法对专用校正场地的依赖性。The operation difficulties of the traditional method of the magnetic compass deviation revises were analyzed. Taking the advantages of satellite orientation, a new method of magnetic compass deviation revises was proposed and its veracity was evaluated. This method can not only predigest the operation of the traditional method, but also can reduce the difficulty and eliminate the reliance of appropriative field. At the same time, this method can insure the veraci ty of traditional method.
