A method and system for generating extended satellite ephemeris data for a satellite for use by a terminal apparatus is described. Historical orbital parameter data (e.g. from historical TLEs) are used to build a predictor for future values of the orbital parameters. The orbital parameter prediction model is then stored on the terminal apparatus (or an existing model can be updated), and at a desired epoch the pre-stored orbital parameter predictor is used to produce estimates of the orbital parameters for the satellite for that epoch (ie synthetic or predicted TLEs). These predicted orbital parameters (predicted TLE) are then used as input to a standard orbit predictor to produce an estimate of the satellite's location, for example to determine satellite pass times. This method allows generation satellite ephemeris data which is valid out to a year or more as compared to the normal validity of ephemeris data of a few hours or days.
