Which of the statements given above is/are correct?
- 1.
IRNSS has three satellites in geostationary and four satellites in geosynchronous orbits.
- 2.

1 and 2 only
2 and 3 only
None
Explanation
IRNSS (NavIC) constellation comprises 7 satellites: 3 in geostationary orbit and 4 in geosynchronous orbit (inclined at 29°), which is correct. IRNSS coverage extends to all of India and about 5500 sq km beyond its borders, providing regional navigation coverage. Statement 3 is incorrect because IRNSS is designed as a regional navigation system for India and the region around it, not a global system like GPS. The system does not provide global coverage. Only statements 1 and 2 are accurate regarding IRNSS specifications and its coverage area. > IRNSS is a regional system (NavIC), not global; 7 satellites total (3 GEO + 4 GSO). Answer: (b).
