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.
