Claim Text:
1. A system implemented in a mobile station, the system comprising: a receiver interface configured to receive real-time orbit data of a first satellite; a correction unit configured to identify at least one real-time clock parameter within the real-time orbit data and to correct an error of a clock bias in predicted orbit data of one or more additional satellites using the at least one real-time clock parameter within the real-time orbit data of the first satellite; and a combining unit configured to combine the real-time orbit data of the first satellite with predicted orbit data, comprising corrected clock bias data that was corrected using the at least one real time clock parameter within the real-time orbit data of the first satellite, of a second satellite in determination of spatial and time information of the mobile station, wherein the first satellite and the second satellite belong to two different satellite systems, and wherein the predicted orbit data has an extended period of validity compared to the real-time orbit data and comprises at least one of 3-D uncertainty values for predicted satellite coordinates or uncertainty values of predicted satellite clock corrections.
