Comparison of several methods of single frequency single epoch GPS ambiguity solution for short baseline
摘要
Abstract
In the paper,the mathematical model of single frequency single epoch GPS ambiguity resolution for short baseline is deeply analyzed,and the methods for settling ill-condition of single epoch normal e-quation are discussed on the basis of the above analysis. Then,several methods of single frequency single epoch GPS ambiguity resolution are put forward and compared. The success rates of these methods for pro-cessing GPS ambiguity are contrastively analyzed. Finally,we come to the conclusion that adopting addi-tional coordinate precision constraint of fixed initial point and at the same time making use of TIKHONOV regularization method can effectively enhance the success rate of single epoch GPS ambiguity solution.关键词
