ISRO GPS System

I am pursing B.E Degree from BITS. I am searching about GPS Aided GEO Augmented Navigation System of ISRO. So is there anyone who will provide details about GPS Aided GEO Augmented Navigation System?

ISRO is committed to provide the satellite based Navigation services to meet the emerging demands of the Civil Aviation requirements.

ISRO is establishing a regional satellite navigation system called Indian Regional Navigation Satellite System (IRNSS).

GPS Aided GEO Augmented Navigation (GAGAN):
It is a Satellite Based Augmentation System (SBAS) implemented jointly with Airport Authority of India (AAI).

Its main objectives are to provide Satellite-based Navigation services with accuracy and integrity required for civil aviation applications.

The GAGAN Signal-In-Space (SIS) is available through GSAT-8 and GSAT-10.

Here I am providing list of all Navigation Satellites of ISRO:
