摘要：
The invention relates to a RAIM algorithm for determining an integrity risk in a GNSS by processing several ranging signals received from satellites of the GNSS wherein the algorithm comprises the following acts:
determining a first group of ranging signals from received ranging signals for determining the integrity risk (S10), wherein a statistical description of each ranging signal of the first group determines the ranging signals as being fault-free,
selecting from the first group of ranging signals at least one ranging signal assuming that the statistical description of this ranging signal is not correct (S12),
determining a second group of ranging signals from the first group by removing the selected at least one ranging signal from the first group of ranging signals (S14), and
determining the integrity risk as the maximum of the integrity risks of all possibilities calculated from the second group of ranging signals at the alert limit (S16).
