GPS is but one form of area nav, just like inertial navigation (through inertial reference units, IRUs), rho-theta navigation (VOR-DME a la King KNS-80) and even rho-rho (DMEDME), all of which are now the province of sophisticated flight management systems (FMS) that consequently provide built-in GPS-independent navigation.
