Ground Based Augmentation System (GBAS), a satellite-based precision approach landing system, is poised to replace the current Instrumental Landing System (ILS) due to its increased precision and cost-effectiveness. GBAS works in conjunction with satellite-based GPS navigation. Notably, a single GBAS Ground Station can serve multiple runways at an airport. DFS Group, a key driver of GBAS implementation, operates multiple stations across Germany. Leveraging their expertise, DFS Aviation Services offers comprehensive support during the transition from ILS to GBAS.
