Union Minister of Civil Aviation launched the GAGAN system (GPS AIDED GEO AUGMENTED NAVIGATION).
What is GAGAN?
Gagan is an indigenous navigational guide system developed by Isro on the lines of GPS system of the US.
Gagan was jointly developed by the Isro and Airports Authority of India (AAI) with a view to assist aircraft in accurate landing.
The Gagan signal is being broadcast through two Geostationary Earth Orbit (GEO) satellites – GSAT8 and GSAT10.
Other uses of GAGAN: To study the ionosphere behavior over the Indian region.
Recently govt said that GAGAN will also be used for warning at unmanned railway crossing signals.

How does GAGAN work?
The GAGAN system consists of a network of 15 Indian Navigation Reference Earth Stations (INRES) spread over the country.
The collected data from them is then sent to 2 Indian Navigation Master Control Centers (INMCC) where computer processing will be done.
INRES sites and INMCCs are connected using Optical Fiber Cable Data Communication Network as well as VSAT link.
GAGAN will provide a precision of 1.5-meter accuracy in the horizontal plane, 2.5-meter in the vertical.

Advantages of GAGAN:
It reduces fuel usage by airplanes
Increases air safety
Increases capacity of airspace. So more airplanes can fly on Indian airspace.
