Abstract: Time-differenced carrier phase (TDCP) is obtained by differencing successive GNSS carrier phase measurements. It can be used to compute precise displacement and velocity, since most of the error sources will be cancelled via sequential differencing. Random sample consensus (RANSAC) algorithm had been introduced to ensure the quality of a multi-GNSS TDCP solution. In this work, we will attempt to demonstrate the feasibility of detecting faults in the TDCP residuals using information extracted from the residuals and outliers observed in a batch of consecutive epochs.
