Google for Z3801A. It's basically a box with a very good crystal oscillator, a GPS receiver, and a pile of software. If the GPS goes down, it coasts on the crystal. How long you can coast depends upon how good your clock is and/or your accuracy requirements. -- These are my opinions, not necessarily my employer's.
