With reference to the Indian Regional Navigation Satellite System (IRNSS), consider the following statements:
1. IRNSS has three Satellites in geostationary and four satellites the geosynchronous orbits.
2. IRNSS covers entire India and about 5500 sq. km beyond its borders.
3. India will have its own satellite navigation system with full global coverage by the middle of 2019.

The Indian Regional Navigation Satellite System (IRNSS), or NavIC, has indeed three satellites in geostationary orbit and four satellites in geosynchronous orbits - making the first statement correct.

The second statement is incorrect as the coverage of IRNSS is not limited to around 5500 sq. km beyond India`s border. In reality, its intent is to provide position accuracy better than 20m within the primary service area that extends up to 1500 km beyond the border of India.

The third statement is also incorrect. IRNSS, as the name infers, is a regional system and it was never intended to provide global coverage. This is contrary to some other systems like Global Positioning System (GPS) by USA, GLONASS by Russia or Galileo by the European Union which are global.

So, the correct answer is 1 only.
