|Abstract:||In this paper, a new ground-based monitor is developed that instantaneously detects all types of orbit ephemeris faults in Ground Based Augmentation Systems (GBAS). Ephemeris faults result in spatial gradients that can be detected using differential GPS measurements across spatially separated ground antennas. The monitor utilizes both carrier phase and pseudorange code measurements from multiple baselines for fault detection. We show that the developed monitor performance exceeds the existing fault detection algorithms and is capable of supporting Category III precision approach and landing.|
