Thats what the AGPS system is, the Almanac and Ephemeris data is provided over a data channel from a server rather than directly from the satellites. The idea being that receiving the data over a dedicated data channel is much quicker than a low-power broadcast from a sat.

This is often confused for a similar mechanism for triangulation of a position using the relative powers of multiple cell towers. This provides a low-resolution position fix suitable for use as the initial seed of the kalman filter (which narrows down the position iteratively).
