Abstract: GNSS receiver clock drift can be estimated as part of the Time Differenced Carrier Phase solution. In this work, a commercial receiver driven by a few configurations of clock is used to estimate the clock drift from multi-constellation GNSS data. Since inauthentic GNSS signals generated with a simulator have an impact on the receiver clock solution, the simulator may be detected or even identified by observing changes in the receiver clock drift solution.
