A comparative study of the integer ambiguity validation procedures
Earth, Planets and Space
In GPS and GLONASS satellite-based positioning, the correct determination of the integer carrier phase ambiguities is the key to achieve precise positioning results. The process of determining the ambiguities, called ambiguity resolution, is usually separated into three steps: (a) estimating the float or real-valued ambiguities, (b) searching the best integer ambiguity set, (c) validating the best ambiguity set. Whilst the theory and methodology for ambiguity estimation and search are welldoi:10.1186/bf03352287 fatcat:t6s5c7nxqrgs7al4c5d34wmvmq
