Discussion on the Ill-Conditioned Problems in Geodetic Surveying

SUN Tong-he,XIANG Nan-ping(School of Info-Physics and Geomantic Engineering of Central South University,Changsha 410083,China)  
Ill-conditioned problems are widely existed in geodetic surveying.To resolve this problem,many experts and scholars both at home and abroad are devoted to the research of the ill-conditioned problems.And they put forward the methods to dealing with the ill-conditioned problems,such as ridge estimation,generalized ridge estimation,principle components estimation,Tihonov regularization,singular value decomposition and virtual observational approach.This paper mainly generalizes the basic principle of these methods,and simply discusses the development of the ill-conditioned problems.
