With reference to the Indian Regional Navigation Satellite System (IRNSS), consider the following statements: 1. IRNSS has three satellites in geostationary and four satellites in 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. Which of the statements given above is/are correct?

Statement 1 is correct because the IRNSS (NavIC) constellation consists of seven satellites, specifically three in geostationary orbits and four in inclined geosynchronous orbits. Statement 2 is incorrect because the system covers an area up to 1,500 km beyond India’s borders, making option (b) the most tempting but wrong choice due to the incorrect distance and unit (5,500 sq. km). The core concept being tested is the technical architecture and specific spatial coverage limits of India’s indigenous regional navigation system.
