Abstract: | Abstract—Time-differenced carrier phase can be computed with measurements and navigation data recorded by a multi-GNSS SDR receiver such as PyChips, from which user displacement and receiver clock drift can be solved. A random sample consensus algorithm has been developed to check consistency among measurements and data. This algorithm can successfully identify inauthentic measurements from a multifrequency GNSS dataset, even if inauthentic satellite orbital/clock data are used. Keywords—inauthentic GNSS, SDR, RANSAC |
