EGPWS uses aircraft inputs such as position, altitude, airspeed and glideslope, along with an internal terrain / obstacle / runway database, to predict potential conflicts between the aircraft's flight path and terrain or an obstacle.
Update to the latest Terrain Database at least twice a year. Updates can be downloaded from the Database Page of the EGPWS web site.
Wire GPS directly to EGPWS. It's simple, uses accurate WGS-84 data and is independent of FMS and RNAV failures.
