IndiGo became the first airline in the country to land aircraft using the indigenous navigation system GAGAN, according to a statement issued on Thursday.
The flight was conducted using an ATR-72 aircraft and landed at the Kishangarh airport in Rajasthan on Wednesday morning, using GPS-aided geo-augmented navigation (GAGAN), which has been jointly developed by the Centre-run Airports Authority of India (AAI) and the Indian Space Research Organisation (ISRO), the statement issued by IndiGo said.
GAGAN is used to provide lateral and vertical guidance when an aircraft is approaching a runway for landing. Its precision is especially useful at small airports where the instrument landing system (ILS) has not been installed.
