Germany’s air navigation service provider (ANSP), Deutsche Flugsicherung (DFS), is working toward the national implementation of differential GPS-based precision approaches in a program expected to last about two years.

Manfred Dieroff, head of noise abatement, environment and navigation at the DFS, told AIN that the company started developing overlay approaches, effectively copies of the conventional procedures, in the mid-1990s. By 1998 it had published stand-alone GPS procedures, and subsequently it approved the use of GPS for nonprecision approaches (NPAs) without the need for conventional navaids.
