Navigation Applications cannot be realised without a Navaid Infrastructure. Unlike 50 years ago, the Navaid infrastructure is now both space- and ground-based.
The ground-based infrastructure refers to the conventional navigation aids such as NDB (Non-Directional Beacon), VOR (Very High Frequency Omni-directional Range), DME (Distance Measuring Equipment) as well as ILS (Instrument Landing System) and MLS (Microwave Landing System).
The space-based infrastructure refers to satellites in orbit around our planet. The generic name for any satellite constellation (and the augmentation systems) used for positioning and time is GNSS (Global Navigation Satellite System).
