中文摘要：
针对GPS快速静态定向中法矩阵严重病态的特点，采用了载波和伪距联合解算及Tikhonov正则化方法，改善了法矩阵的病态性，实际算例表明该方法是有效的、可行的。
英文摘要：
In rapid static GPS heading system,the normal equation matrix based on the least square estimation is often ill-posed . Two methods are presented to solve the problem. One is combinaton of phase and code observations so as to add the information. The other is Tikhonov regularization method. The result of numerical analysis shows that the two method resolve well the ill-posed problem,and tthey are right and feasible.
