    摘要： A Global Navigation Satellite System receiver (102) comprising at least one processor (104) is provided. The processor is configured to: determine a weighted false alarm probability allocation for at least one sub-solution in a solution separation based integrity monitoring module (130), wherein the weighted false alarm probability allocation is based on pre-determined values for missed detection probability and fault probability for the sub-solution, wherein the at least one sub-solution is created by excluding a set of potentially faulty satellites from a full solution, wherein a fault mode occurs when there is a faulty satellite in the excluded set of potentially faulty satellite, wherein the at least one sub-solution's missed detection probability is probability that detection of associated fault mode occurrence in a sub-solution was missed, and wherein the at least one sub-solution's fault probability is probability that the fault mode occurs; compute a weighted protection level based on the weighted false alarm probability.

    摘要： The present disclosure provides a method for reducing an impact of signal anomalies on a device for position detection in a global navigation system, which includes a plurality of space vehicles transmitting navigation signals to the device for position detection. The method includes the steps of:
    1) receiving, by the device, a first group of navigation signals from the space vehicles, each navigation signal having an integrity risk contribution associated thereto;
    2) calculating, by the device, at least one first overall integrity of the first group of navigation signals based on their associated integrity risk contributions, the method further including,
    3) if the at least one first overall integrity is below a first predetermined threshold, determining a position of the device; or
    4) if at least one first overall integrity exceeds the first predetermined threshold,
    4a) removing n navigation signals having the highest integrity risk contributions from the first group to obtain a second group of navigation signals, n being a natural number;
    4b) determining the position of the device based on the group of navigation signals obtained in step 4a).

    摘要： Methods and apparatus to monitor GPS/GNSS atomic clocks are disclosed. An example method includes establishing a measured difference between an atomic frequency standard (AFS) and a monitoring device. The method also includes modeling an estimated difference model between the AFS and the monitoring device, and computing a residual signal based on the measured difference and the estimated difference model. In addition, the method includes analyzing, by a first detector, the residual signal at multiple thresholds, each of the thresholds having a corresponding persistency defining the number of times a threshold is exceeded before one or more of a phase jump, a rate jump, or an acceleration error is indicated. Furthermore, the method includes analyzing, by a second detector, a parameter of the estimated difference model at multiple thresholds, each of the thresholds having a corresponding persistency defining the number of times a drift threshold is exceeded before a drift is indicated.
