|Abstract:||Application of fault detection and exclusion based on random sample consensus (RANSAC) is demonstrated on a GNSS carrier phase solution. Multi-constellation carrier phase measurements were extracted from flight test data and ground-vehicle data, based on which average velocity was computed by using time-differenced carrier phase. An uncertainty model has been developed to predict the accuracy, the integrity and continuity risks and the vertical protection levels associated with the velocity solution under different operational conditions. The validity of the model also depends on a good understanding of the actual satellite faults that may originate from the space, control or user segments.|
