What is VOR?
VOR stands for VHF Omnidirectional Range, a ground-based radio navigation system widely used in aviation across India and worldwide. Operating in the very high frequency band between 108 and 117.95 MHz, it provides aircraft with continuous bearing information relative to a fixed ground station, allowing pilots to determine their position and follow designated air routes with precision. The system works by transmitting a rotating directional signal that aircraft receivers interpret to display their radial position from the station. In India, the Airports Authority of India operates and maintains an extensive network of VOR stations at major airports including Delhi, Mumbai, Chennai, and Kolkata, along with key air corridors connecting regional centres, supporting both civilian and military flight operations. Pilots rely on VOR signals during en-route navigation, standard instrument departures, and approach procedures, particularly when flying through poor weather or low visibility conditions. The system remains a cornerstone of air traffic management infrastructure in the country, working alongside DME and ILS to ensure safer skies. For students preparing for aviation, engineering, or defence examinations, understanding VOR technology is essential as questions on radio navigation aids frequently appear in DGCA, AFCAT, and civil services technical sections.

What is the full form of VOR?
VOR stands for VHF Omnidirectional Range, a ground-based radio navigation system used in aviation to provide aircraft with bearing information.
How does VOR work in Indian aviation?
VOR ground stations transmit signals that aircraft receivers use to determine their bearing and position relative to the station, helping pilots navigate along established air routes across India.
Where are VOR stations located in India?
The Airports Authority of India operates VOR stations at major airports such as Delhi, Mumbai, Chennai, Kolkata, Hyderabad, and Bengaluru, along with other key air corridors throughout the country.
