| Abstract: | 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. |
