Building a trackside augmentation network can provide more accurate GNSS positioning information for rail transit. In order to ensure the high safety requirements of rail transit, it is necessary to ensure the integrity of the augmented data provided by the trackside augmentation network. In this paper, a joint integrity monitoring algorithm is proposed, which simultaneously detects faulty satellites at the reference station level and at the reference station network level, and uses the long-term observation data of the reference station to calculate a predetermined threshold to obtain a healthy satellite and reference base station combination.
