What navigation system combines VHF Omnirange, localizer, and glideslope for use with ground stations?

The navigation system that combines VHF Omnirange, localizer, and glideslope for use with ground stations is known as the Instrument Landing System (ILS). This system provides precise guidance to aircraft during the approach and landing phases, particularly in conditions of reduced visibility.

The VHF Omnirange (VOR) part of the ILS provides horizontal guidance to help pilots determine their location relative to the runway. The localizer component provides the necessary lateral guidance, ensuring the aircraft is aligned with the runway centerline. The glideslope provides vertical guidance, helping pilots maintain the correct descent angle to land safely.

Other systems mentioned, such as the Tactical Air Navigation System (TACAN) and Global Positioning System (GPS), are also used for navigation but employ different technologies and do not specifically integrate the functions of VHF Omnirange, localizer, and glideslope in the context of approach and landing. TACAN, for instance, is primarily used by military aircraft and provides range and bearing information, while GPS is a satellite-based system offering global navigation capabilities, but does not focus on these specific approach parameters used in ILS.

Thus, the answer was focused on the complete integration needed for precise landing guidance in aviation, which
