Abstract
Abstract A method and apparatus for providing a satellite tracking data that is valid for an extended period of time into the future. At least a portion of the satellite tracking data is formatted into a format prescribed by a remote receiver. The formatted data is transmitted to the remote receiver via a distribution network. As such, a remote receiver may accurately operate for days without receiving an update of the satellite tracking data.
