Ambiguity validation with Ratio test based on reliability index
Jian Deng · Cehui kexue · 2013
Ambiguity validation is very important to positioning precision of satellite navigation.According to the difficulty in choosing the c value in Ratio test for ambiguity validation,a method was proposed in the paper.Firstly,the probability characteristic of Ratio test was analyzed based on the theory of success rate;and then the functional relationship between the fixed failure rate and c value was deduced so as to determine the c value and ensure the ambiguity validation.Experiment showed that this method could solve the key problem of Ratio test and have some applicable value.
