摘　　要：研究了ALPHA导航差分修正数据、差分定位的概念,给出了差分修正及差分定位数学算法,并通过这些算法得到了差分修正数据,使ALPHA导航系统的定位精度与使用预测修正法时相比提高了一个数量级。In this paper, the conceptions of difference correction and orientation were studied. And their algorithms were put forward, through which high quatity data of difference correctio were obtained. Compared to the precision when using forecast correction, orientation correction improves the precision of ALPHA system by 10 times.
