The correct answer is option 1: 1 only.

GAGAN (GPS Aided Geo Augmented Navigation) is a satellite-based navigation system developed jointly by the Indian Space Research Organisation (ISRO) and the Airports Authority of India (AAI). It provides highly precise satellite navigation signals over Indian airspace.

Statement 1 is correct. GAGAN offers enhanced satellite navigation signals that are ten times more precise than GPS. This makes it a valuable tool for various applications such as aviation, maritime navigation, tracking, surveying, and mapping.

Statement 2 is incorrect. GAGAN was not developed jointly by ISRO and NASA. It was developed by ISRO and AAI, with some technical support from Raytheon, an American defense contractor. NASA has its own satellite navigation system called GPS (Global Positioning System).

In summary, GAGAN offers highly precise satellite navigation signals over India, but it was not developed jointly by ISRO and NASA.
