    摘要: A device for detection of falsified signals in a satellite navigation system includes at least two antennas having one or more receivers for receiving navigation signals, a phase difference measuring unit for determining phase differences of the received navigation signals for each antenna, and a detection unit for detecting falsified navigation signals among the received navigation signals on the basis of the phase differences determined.

    摘要: A method for determining the integrity risk at an alert limit of a position solution determined with a satellite navigation system involves calculating a first integrity risk at the alert limit assuming that one satellite j of the satellites is faulty. A first position solution is determined with the signals from all of the satellites and a second position solution is determined with the signals from all of the satellites except for the signal received from the satellite j. A difference between the first and the second position solution is identified and subtracted from the alert limit to create a reduced alert limit. A second integrity risk at the reduced alert limit is calculated with the signals received from all satellites except the signal received from the satellite j. The integrity risk at the alert limit is determined using the minimum of the first and second integrity risks.

    摘要: In a satellite-based augmentation system a data stream is generated that includes user messages having different message types. A plurality of predetermined unique sequences of message types are formed and each formed sequence is allocated to one of a plurality of data sources that are used for generating user messages in the satellite-based augmentation system. A data source is selected for generating a data stream that includes user messages. The selected data source generates the data stream including user messages by using the predetermined unique sequence of message types that is allocated to the selected data source.
