摘要
Devices and methods are described for determining position information without broadcast ephemeris data for extended time periods. A client device is disclosed that stores satellite states determined from broadcast ephemeris and numerically integrates equations of motion with regard to the stored satellite states to determine current satellites states. The client device uses the current satellite states in conjunction with received satellite signals to determine where the satellite signals were received.
